TO BE HELD ON JUNE 8, 2009
 
 
Dear Stockholder:
 
You are cordially invited to attend the 2009 Annual Meeting of Stockholders of Power Integrations, Inc., a Delaware corporation. The meeting will be held on Monday, June 8, 2009 at 10:00 a.m., local time, at our executive offices located at 5245 Hellyer Avenue, San Jose, California 95138 for the following purposes:
 
1. To elect our eight nominees as directors to serve until the 2010 Annual Meeting of Stockholders and their successors are duly elected and qualified.
 
2. To ratify the selection by the Audit Committee of the Board of Directors of Deloitte & Touche LLP as the independent registered public accounting firm of Power Integrations, Inc. for the fiscal year ending December 31, 2009.
 
3. To conduct any other business properly brought before the meeting.
 
These items of business are more fully described in the Proxy Statement accompanying this Notice.
 
 
Important Notice Regarding the Availability of Proxy Materials for the Annual Meeting of Stockholders to Be Held on June 8, 2009 at 10:00 a.m. at 5245 Hellyer Avenue, San Jose, California 95138
 
The proxy statement and annual report to stockholders are available at www.edocumentview.com/POWI.
 
The Board of Directors recommends that you vote FOR the proposals identified above.
 
 
We are mailing to most of our stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) instead of a paper copy of this proxy statement and our 2008 Annual Report. The Notice contains instructions on how to access those documents over the internet. The Notice also contains instructions on how to request a paper copy of our proxy materials, including this proxy statement, our 2008 Annual Report and a form of proxy card or voting instruction card. All stockholders who do not receive a Notice will receive a paper copy of the proxy materials by mail. We believe that this process will allow us to provide our stockholders with the information they need in a timelier manner, while reducing the environmental impact and lowering the costs of printing and distributing our proxy materials.
 
The record date for the Annual Meeting is April 22, 2009. Only stockholders of record at the close of business on that date may vote at the meeting or any adjournment thereof.
 
By Order of the Board of Directors

You are cordially invited to attend the meeting in person. Whether or not you expect to attend the meeting, please complete, date, sign and return a proxy card, or vote over the telephone or the internet as instructed in these materials, as promptly as possible in order to ensure your representation at the meeting. Even if you have voted by proxy, you may still vote in person if you attend the meeting. Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to vote at the meeting, you must obtain a proxy issued in your name from that record holder.

PROXY STATEMENT FOR THE 2009
ANNUAL MEETING OF STOCKHOLDERS
June 8, 2009
 
 
 
QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING
 
Why am I receiving these materials?
 
The Board of Directors of Power Integrations, Inc. is soliciting your proxy to vote at the 2009 Annual Meeting of Stockholders, including at any adjournments or postponements of the meeting. You are invited to attend the annual meeting to vote on the proposals described in this proxy statement. However, you do not need to attend the meeting to vote your shares. Instead, you may simply complete, sign and return a proxy card, or follow the instructions below or in the Notice (as defined below) to submit your proxy over the telephone or on the internet.
 
Why did I receive a Notice in the mail regarding the availability of proxy materials on the internet?
 
We are pleased to take advantage of rules of the Securities and Exchange Commission (the “SEC”) that allow companies to furnish their proxy materials over the internet. Accordingly, we are sending to most of our stockholders of record a Notice of Internet Availability of Proxy Material (the “Notice”) on or about April 27, 2009. All stockholders will have the ability to access the proxy materials on the website referred to in the Notice or request to receive a printed set of the proxy materials. Instructions on how to access the proxy materials over the internet or to request a printed copy may be found in the Notice. In addition, stockholders may request to receive proxy materials in printed form or electronically by email on an ongoing basis. A stockholder’s election to receive proxy materials by mail or email will remain in effect until the stockholder terminates it.
 
We intend to mail the Notice on or about April 27, 2009 to all stockholders of record entitled to vote at the annual meeting.
 
Will I receive any other proxy materials by mail?
 
We may (but are not required to) send you a proxy card, along with a second Notice, on or after May 7, 2009.
 
Who can vote at the annual meeting?
 
Only stockholders of record at the close of business on April 22, 2009 will be entitled to vote at the annual meeting. On this record date, there were 26,927,509 shares of common stock outstanding and entitled to vote.
 
Stockholder of Record: Shares Registered in Your Name
 
If on April 22, 2009 your shares were registered directly in your name with Power Integrations’ transfer agent, Computershare, then you are a stockholder of record. As a stockholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the meeting, we urge you to fill out and return the enclosed proxy card or vote by proxy over the telephone or on the internet as instructed below or in the Notice to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank
 
If on April 22, 2009 your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are, or the Notice is, being forwarded to you by that organization. The organization holding your account is considered to be the stockholder of record for purposes of voting at the annual meeting. As a beneficial owner, you have the right to direct your broker or other agent regarding how to vote the shares in your account. You are also invited to attend the annual meeting. However, since you are not the stockholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker or other agent.
 
What am I voting on?
 
There are two matters scheduled for a vote:
 
  •  Election of our eight nominees as directors to serve until the 2010 Annual Meeting of Stockholders and until their successors are duly elected and qualified; and
 
  •  Ratification of the selection by the Audit Committee of the Board of Directors of Deloitte & Touche LLP as the independent registered public accounting firm of Power Integrations, Inc. for its fiscal year ending December 31, 2009.
 
What if another matter is properly brought before the meeting?
 
The Board of Directors knows of no other matters that will be presented for consideration at the Annual Meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.
 
Why didn’t I receive a Notice in the mail regarding the Internet availability of proxy materials?
 
We are providing stockholders who have previously requested to receive paper copies of the proxy materials with paper copies of the proxy materials instead of a Notice. If you would like to reduce the costs incurred by us in mailing proxy materials, you can consent to receiving all future proxy statements, proxy cards and annual reports electronically via email or the internet. To sign up for electronic delivery, please follow the instructions provided in your Notice, or if you received a printed version of the proxy materials by mail, by following the instructions provided with your proxy materials and on your proxy card or voting instruction card, to vote using the internet and, when prompted, indicate that you agree to receive or access stockholder communications electronically in future years. Alternatively, you can go to www.envisionreports.com/POWI and enroll for online delivery of annual meeting and proxy voting materials.
 
Can I vote my shares by filling out and returning the Notice?
 
No. The Notice will, however, provide instructions on how to vote by internet, by telephone, by requesting and returning a paper proxy card, or by submitting a ballot in person at the meeting.
 
How do I vote?
 
You may either vote “For” all the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify. For each of the other matters to be voted on, you may vote “For” or “Against” or abstain from voting. The procedures for voting are as follows:
 
Stockholder of Record: Shares Registered in Your Name
 
If you are a stockholder of record, you may vote in person at the annual meeting, vote by proxy using a proxy card (which is enclosed if you received this proxy statement by mail or that you may request or that we may elect to deliver at a later time), vote by proxy over the telephone, or vote by proxy on the internet. Whether or not you plan to attend the meeting, we urge you to vote by proxy to ensure your vote is counted. You may still attend the meeting and vote in person if you have already voted by proxy.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

Simply complete and mail the proxy card or follow the voting instructions in the Notice to ensure that your vote is counted. Alternatively, you may vote by telephone or over the internet as instructed by your broker or bank. To vote in person at the annual meeting, you must obtain a valid proxy from your broker, bank, or other agent.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.
 
How many votes do I have?
 
On each matter to be voted upon, you have one vote for each share of common stock you own as of April 22, 2009.
 
What if I return a proxy card or otherwise vote but do not make specific choices?
 
If you return a signed and dated proxy card or otherwise vote without marking voting selections, your shares will be voted, as applicable, “For” the election of all eight nominees for director and “For” the ratification of the Audit Committee’s selection of Deloitte & Touche LLP as the independent registered public accounting firm of Power Integrations for its fiscal year ending December 31, 2009. If any other matter is properly presented at the meeting, your proxy holder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.
 
Who is paying for this proxy solicitation?
 
We will pay for the entire cost of soliciting proxies. In addition to these proxy materials, our directors and employees together with representatives of the Altman group may also solicit proxies in person, by telephone, or by other means of communication. Directors and employees will not be paid any additional compensation for soliciting proxies but The Altman Group will be paid its customary fee of approximately $6,000, plus out-of-pocket expenses if it solicits proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one Notice or set of proxy materials?
 
If you receive more than one Notice or set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions on the proxy cards in the proxy materials or Notices to ensure that all of your shares are voted.
 
Can I change my vote after submitting my proxy?
 
Yes. You can change your vote or revoke your proxy at any time before the final vote at the meeting. If you are the record holder of your shares, you may change your vote or revoke your proxy in any one of the following ways:
 
o You may submit another properly completed proxy card with a later date.
 
o You may vote again over the internet or by telephone.
 
o You may send a timely written notice that you are revoking your proxy to Power Integrations’ Secretary at 5245 Hellyer Avenue, San Jose, California 95138-1002.
 
o You may attend the annual meeting and vote in person. Simply attending the meeting will not, by itself, revoke your proxy.
 
Your most current proxy card or telephone or internet proxy is the one that is counted.
 
If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.
 
When are stockholder proposals due for next year’s annual meeting?
 
To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing by December 28, 2009 to our Corporate Secretary at 5245 Hellyer Avenue, San Jose, California 95138-1002; provided, however, that if our 2010 Annual Meeting of Stockholders is held before May 9 or after July 8, 2010, then the deadline is a reasonable amount of time prior to the date we begin to print and mail our proxy statement for the 2010 Annual Meeting of Stockholders. If you wish to submit a proposal that is not to be included in next year’s proxy materials or nominate a director pursuant to our Bylaws, you must provide specified information in writing to our Corporate Secretary at the address above by December 28, 2009, except that if our 2010 Annual Meeting of Stockholders is held before May 9 or after July 8, 2010, notice by the stockholder to be timely must be received not later than the close of business on the tenth day following the day on which such public announcement of the date of such meeting is made. You are also advised to review our Bylaws, which contain a description of the information required to be submitted as well as additional requirements about advance notice of stockholder proposals and director nominations.
 
How are votes counted?
 
Votes will be counted by the inspector of election appointed for the meeting, who will separately count “For” and “Withhold” and, with respect to proposals other than the election of directors, “Against” votes, abstentions and broker non-votes. Abstentions will be counted towards the vote total for each proposal, and will have the same effect as “Against” votes. Broker non-votes have no effect and will not be counted towards the vote total for any proposal.
 
What are “broker non-votes”?
 
Broker non-votes occur when a beneficial owner of shares held in “street name” does not give instructions to the broker or nominee holding the shares as to how to vote on matters deemed “non-routine”. In such cases, the shares are determined to be “present” for purposes of determining whether a quorum is present, but are not counted for purposes of any vote.
 
Generally, if your shares are held by your broker as your nominee (that is, in “street name”), you, as the beneficial owner of the shares, are entitled to give voting instructions to the broker or nominee holding the shares. To do so, you will need to obtain a proxy form or notice of how to vote over the internet or by telephone from the institution that holds your shares and follow the instructions included on that form or notice regarding how to instruct your broker to vote your

shares. If you do not give instructions to your broker, your broker can vote your shares with respect to “routine” items, but not with respect to “non-routine” items. Under the rules and interpretations of the New York Stock Exchange (“NYSE”), “non-routine” matters are generally those involving a contest or a matter that may substantially affect the rights or privileges of shareholders, such as mergers or shareholder proposals.
 
How many votes are needed to elect directors?
 
For the election of our eight nominees as directors, the eight nominees receiving the most “For” votes (among votes properly cast in person or by proxy and entitled to vote on the election of directors) will be elected. Only votes “For” or “Withheld” will affect the outcome.
 
Pursuant to our Corporate Governance Guidelines, our Board will nominate for re-election as director in an uncontested election of directors only those candidates who have tendered an irrevocable resignation as a director, which resignation shall be conditioned upon both (A) such director failing to have received more “For” votes than “Withheld” votes in an uncontested election and (B) acceptance by the Board of such resignation.
 
If, in an uncontested election, a director fails to have received more “For” votes than “Withheld” votes for election, then, within 90 days following certification of the stockholder vote, the Nominating and Governance Committee will act to determine whether to accept the director’s conditional resignation and will submit such recommendation for prompt consideration by the Board, and the Board will act on the Nominating and Governance Committee’s recommendation. The Nominating and Governance Committee and the Board may consider any factors they deem relevant in deciding whether to accept a director’s conditional resignation.
 
As a result, although a director who receives more “Withheld” votes than “For” votes in an uncontested election will be elected as a director, that director may cease to be a director if the Board determines that, based on the fact that the director received more “Withheld” votes than “For” votes, and the other facts the Board may deem relevant, the Board decides to accept a director’s conditional resignation.
 
How many votes are needed to ratify the Audit Committee’s selection of Deloitte & Touche LLP as our independent auditors?
 
To be approved, ratification of Deloitte & Touche LLP as the independent registered public accounting firm of Power Integrations, Inc. for its fiscal year ending December 31, 2009, must receive a “For” vote from the holders of a majority of shares voting either in person or represented by proxy and entitled to vote. If you “Abstain” from voting, it will have the same effect as an “Against” vote. Broker non-votes will have no effect.
 
What is the quorum requirement?
 
A quorum of stockholders is necessary to hold a valid meeting. A quorum will be present if stockholders holding at least a majority of the outstanding shares entitled to vote are present at the meeting in person or represented by proxy. On the record date, there were 26,927,509 shares outstanding and entitled to vote. Thus the holders of 13,463,755 shares must be present in person or represented by proxy at the meeting to have a quorum.
 
Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other nominee) or if you vote in person at the meeting. Abstentions and broker non-votes will be counted towards the quorum requirement. If there is no quorum, the chairman of the meeting or the holders of a majority of the shares present at the meeting in person or represented by proxy may adjourn the meeting to another date.
 
How can I find out the results of the voting at the annual meeting?
 
Preliminary voting results will be announced at the annual meeting. Final voting results will be published in Power Integrations’ quarterly report on Form 10-Q for the second quarter of 2009.
 
What proxy materials are available on the internet?
 
The letter to stockholders, proxy statement, and annual report to stockholders are available at www.edocumentview.com/POWI.

Proposal 1
 
Election Of Directors
 
Power Integrations’ Board of Directors (the “Board”) is elected annually at the annual meeting. Vacancies on the Board may be filled only by persons elected by a majority of the remaining directors. A director elected by the Board to fill a vacancy shall serve for the remainder of the year, and until the director’s successor is duly elected and qualified. This includes vacancies created by an increase in the number of directors.
 
The Board presently has eight members, all of whose terms of office expire at the annual meeting. Proxies may not be voted for a greater number of persons than the number of nominees named.
 
Each of the nominees listed below is currently a director of Power Integrations who was previously elected by the stockholders, other than Dr. George. Dr. George commenced service as a director on March 9, 2009, and was recommended by a non-management director. If elected at the Annual Meeting, each of these nominees would be elected and qualified to serve until the 2010 Annual Meeting of Stockholders and until his successor is duly elected and qualified, or, if sooner, until the director’s death, resignation or removal. It is Power Integrations’ policy to encourage directors and nominees for director to attend the Annual Meeting. Three of the current directors attended the 2008 Annual Meeting of Stockholders.
 
Directors are elected by a plurality of the votes of the holders of shares present in person or by proxy and entitled to vote on the election of directors. Unless marked otherwise we will vote proxies returned to us for the nominees named below. The eight nominees receiving the highest number of affirmative votes will be elected. If a nominee receives more “Withheld” votes than “For” votes, then notwithstanding the election of that nominee, if our Board determines that, based on the fact that the director received more “Withheld” votes than “For” votes, and the other facts the Board may deem relevant, our Board may decide to accept the nominee’s conditional resignation previously submitted as required under our Corporate Governance Guidelines. See “How many votes are needed to elect directors?” on page 5 for a description of these guidelines. If any nominee becomes unavailable for election as a result of an unexpected occurrence, your shares will be voted for the election of a substitute nominee proposed by Power Integrations. Each person nominated for election has agreed to serve if elected. Power Integrations’ management has no reason to believe that any nominee will be unable to serve.

The Board Recommends
A Vote In Favor Of Each Named Nominee.
 
Independence of The Board of Directors
 
As required under the Nasdaq Stock Market (“Nasdaq”) listing standards, a majority of the members of our Board must qualify as “independent,” as affirmatively determined by our Board. The Board consults with Power Integrations’ counsel to ensure that the Board’s determinations are consistent with all relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the Nasdaq, as in effect from time to time.
 
Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his family members, and Power Integrations, its senior management and its independent registered public accounting firm, the Board affirmatively has determined that all of the directors, other than Mr. Balakrishnan, our president and chief executive officer, are independent directors within the meaning of the applicable Nasdaq listing standards. In making this determination, the Board found that none of the directors or nominees for director other than Mr. Balakrishnan had a material or other disqualifying relationship with Power Integrations. Mr. Balakrishnan, by virtue of being Power Integrations’ president and chief executive officer, is not an independent director.
 
Information Regarding the Board and its Committees
 
The Board has adopted Corporate Governance Guidelines to help assure that the Board will have the necessary authority and practices in place to make decisions that are independent of Power Integrations’ management. The guidelines are also intended to align the interests of directors and management with those of Power Integrations’ stockholders. The Corporate Governance Guidelines set forth the practices the Board will follow with respect to, among other things, Board composition and selection, Board meetings and involvement of senior management, chief executive officer performance evaluation and succession planning, Board committees and compensation and director education and orientation. The Corporate Governance Guidelines are available on our website, which is www.powerint.com.
 
The Board has an Audit Committee, a Compensation Committee and a Nominating and Governance Committee.

Compensation Committee
 
The Compensation Committee of the Board reviews and approves the overall compensation strategy and policies for Power Integrations. For this purpose, the Compensation Committee performs several functions, including:
 
  •  with respect to the chief executive officer, reviews and approves all compensation, including incentive-based compensation and equity compensation awards, and develops or reviews annual performance objectives and goals relevant to compensation and awards and evaluates the performance of the chief executive officer in light of these goals and objectives;
 
  •  reviews incentive-based compensation plans in which our executive officers participate, and determines the salaries, incentive and equity compensation for executive officers, and oversees the evaluation of management;

Compensation Committee Processes and Procedures
 
The Compensation Committee of the Board determines all compensation for our executive officers, including our chief executive officer. The Compensation Committee also administers our compensation plans, including equity incentive plans, and makes recommendations to the Board regarding the adoption, amendment, and termination of these compensation plans. The Compensation Committee also analyzes, considers and recommends to the Board the compensation to be paid to our non-employee directors for their service on the Board and its committees, other than compensation received pursuant to automatic equity award grants under stockholder-approved equity compensation plans.
 
The Compensation Committee has the authority to obtain advice or assistance from consultants, legal counsel, accounting or other advisors as appropriate, to perform its duties, and to determine the terms, costs and fees for such engagements, which are paid for by Power Integrations. The Compensation Committee also has full access to all books, records, facilities and personnel of Power Integrations.
 
The Compensation Committee meets as often as it deems appropriate, but not less frequently than once each year to review the compensation and awards of the executive officers and other employees of Power Integrations, and otherwise perform its duties under its charter.
 
Our chief executive officer reviews with the Compensation Committee on a regular basis our compensation philosophy and programs, including named executive officers, so that the Compensation Committee can recommend any changes necessary to keep our compensation philosophy and programs aligned with our business objectives. Mr. Balakrishnan, our chief executive officer, makes recommendations to the Compensation Committee with respect to the compensation of the named executive officers. The Compensation Committee also utilizes an outside compensation consultant to provide it with advice on competitive compensation plans. The Compensation Committee considers, but is not bound to and does not always accept, management’s or the outside consultant’s recommendations with respect to executive compensation. The Compensation Committee discusses Mr. Balakrishnan’s compensation with him, but deliberates and makes decisions with respect to Mr. Balakrishnan’s compensation without him present.
 
Mr. Balakrishnan and other executive officers attend some of the Compensation Committee’s meetings, but leave the meetings as appropriate when matters of executive compensation specific to them are discussed.
 
The Compensation Committee aligns cash and equity compensation to market comparables. The Compensation Committee selects peer companies on the basis of fiscal and business similarities to Power Integrations. The Compensation Committee analyzes market compensation practices annually using the most directly relevant published survey sources available. In 2008, the Compensation Committee engaged an independent compensation consulting firm, Meyercord & Associates, Inc. (“Meyercord”), to assist in the analysis of compensation survey data. Meyercord attends Compensation Committee meetings from time to time and provides peer group analysis, feedback and recommendations to the Compensation Committee. In addition to survey data, the Compensation Committee analyzes information reported in peer companies’ SEC filings for all elements of compensation, including salary, cash incentive compensation and equity compensation.
 
Our Board determines outside director compensation, after receiving the recommendations from the Compensation Committee and the same independent consultant engaged by the Compensation Committee and used by the Compensation Committee in connection with determining executive officer compensation.
 
A further description of the Compensation Committee processes and procedures and the specific determinations of the Compensation Committee with respect to executive compensation for fiscal years 2008 and 2009 are described in greater detail in the Compensation Discussion and Analysis section of this proxy statement.
 
Nominating and Governance Committee
 
The Nominating and Governance Committee of the Board is responsible for recommending the nomination of directors to the Board and for establishing and monitoring our corporate governance. For this purpose, the Nominating and Governance Committee performs several functions, including:
 
  •  evaluates and recommends to the Board director nominees for each election of directors;


11


Table of Contents

 
  •  determines criteria for selecting new directors, including desired board skills and attributes, and identifies and actively seeks individuals qualified to become directors;
 
  •  considers nominations of director candidates validly made by stockholders;
 
  •  reviews and makes recommendations to the Board concerning qualifications, appointment and removal of committee members;
 
  •  develops, recommends for Board approval, and reviews on an ongoing basis the adequacy of, Power Integrations’ corporate governance principles;
 
  •  assists the Board in developing criteria for the evaluation of the Board and committee performance; and
 
  •  considers Board nominees and proposals submitted by stockholders and establishes any policies, processes and procedures, including procedures to facilitate stockholder communication with the Board.
 
The Board has adopted a written Nominating and Governance Committee Charter, which can be found on our website at www.powerint.com. As of the date of this proxy, four directors comprise the Nominating and Governance Committee: Messrs. Brathwaite and Iyer and Drs. Fiebiger and George. All members of the Nominating and Governance Committee are independent (as independence is currently defined in Rule 4200(a)(15) of the Nasdaq listing standards).
 
The Nominating and Governance Committee believes that candidates for director should have certain minimum qualifications, including being able to read and understand basic financial statements, being over 21 years of age and having the highest personal integrity and ethics. The Nominating and Governance Committee also intends to consider such factors as possessing relevant expertise upon which to be able to offer advice and guidance to management, having sufficient time to devote to the affairs of Power Integrations, having demonstrated experience in his or her field, having the ability to exercise sound business judgment and having the commitment to rigorously represent the long-term interests of Power Integrations’ stockholders.
 
Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of Power Integrations and the long-term interests of stockholders. In conducting this assessment, the Nominating and Governance Committee considers the criteria for director qualifications set by the Board, as well as diversity, age, skill, and such other factors as it deems appropriate given the current needs of the Board and Power Integrations, to maintain a balance of knowledge, experience and capability. In the case of incumbent directors whose terms of office are set to expire, the Nominating and Governance Committee reviews such directors’ overall service to Power Integrations during their term, including the number of meetings attended, level of participation, quality of performance and any other relationships and transactions that might impair such directors’ independence. In the case of new director candidates, the Nominating and Governance Committee also determines whether the nominee must be independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board. The Nominating and Governance Committee meets to discuss and consider such candidates’ qualifications and then recommends a nominee to the Board by majority vote. To date, the Nominating and Governance Committee has not paid a fee to any third party to assist in the process of identifying or evaluating director candidates. To date, the Nominating and Governance Committee has not rejected a timely director nominee from a stockholder or stockholders holding more than 5% of our voting stock. Moreover, pursuant to a litigation settlement, Power Integrations has solicited nominations for an independent director from stockholders of Power Integrations who own a total of 5% or more of the outstanding shares of Power Integrations’ common stock, based on Schedule 13-Ds and Schedule 13-Gs on file with the Securities and Exchange Commission at the time of the solicitation.
 
The Nominating and Governance Committee will consider director candidates recommended by stockholders. The Nominating and Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether the candidate was recommended by a stockholder

The Board met twelve times in 2008. All directors attended at least 75% of the aggregate number of the meetings of the Board and of the committees on which they served, held during the portion of the last fiscal year for which they were directors or committee members in 2008.
 
As required under applicable Nasdaq listing standards, in fiscal 2008, the company’s independent directors met in regularly scheduled executive sessions at which only independent directors were present.

Stockholders who wish to communicate with the Board may do so by sending written communications addressed as follows: Power Integrations Board Communication, 5245 Hellyer Avenue, San Jose, California 95138-1002. Any communication sent must state the number of shares owned by the security holder making the communication. The communications will be reviewed by the chairman of the Board.

Code of Business Conduct and Ethics
 
Power Integrations has adopted the Power Integrations, Inc. Code of Business Conduct and Ethics that applies to all officers, directors and employees.

Proposal 2
 
Ratification Of Selection Of
Independent Registered Public Accounting Firm
 
The Audit Committee of the Board has selected Deloitte & Touche LLP as Power Integrations’ independent registered public accounting firm for the fiscal year ending December 31, 2009, and the Board has directed that management submit the selection of Deloitte & Touche LLP as Power Integrations’ independent registered public accounting firm for ratification by the stockholders at the annual meeting. Deloitte & Touche LLP has audited Power Integrations’ financial statements since 2005. Representatives of Deloitte & Touche LLP are expected to be present at the annual meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.
 
Neither Power Integrations’ Bylaws nor other governing documents or law require stockholder ratification of the selection of Deloitte & Touche LLP as Power Integrations’ independent registered public accounting firm. However, the Board is submitting the selection of Deloitte & Touche LLP to the stockholders for ratification as a matter of good corporate practice. If the stockholders fail to ratify the selection, the Audit Committee will reconsider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee in its discretion may direct the appointment of a different independent registered public accounting firm at any time during the year if they determine that such a change would be in the best interests of Power Integrations and its stockholders.
 
The affirmative vote of the holders of a majority of the shares present in person or represented by proxy and entitled to vote at the annual meeting will be required to ratify the selection of Deloitte & Touche LLP. Abstentions will be counted toward the tabulation of votes cast on proposals presented to the stockholders and will have the same effect as negative votes. Broker non-votes are counted towards a quorum, but are not counted for any purpose in determining whether this matter has been approved.

In addition, the Audit Committee may delegate to one or more members of the committee the authority to grant pre-approvals for such audit and non-audit services, provided that (1) the decisions of such member(s) to grant any such pre-approval shall be presented to the Audit Committee at its next scheduled meeting and (2) the Audit Committee has established policies and procedures for such pre-approval of services consistent with the requirements of clauses (a) and (b) above.

Report of The Audit Committee of The Board*
 
During 2008, three non-employee directors, Mr. Bickell, Mr. Iyer and Dr. Fiebiger, comprised the Audit Committee.
 
Management is responsible for Power Integrations’ internal controls and the financial reporting process. The independent registered public accounting firm is responsible for performing an independent audit of Power Integrations’ consolidated financial statements in accordance with generally accepted auditing standards and to issue a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes.
 
In this context, the Audit Committee has reviewed and discussed the audited consolidated financial statements for the fiscal year ended December 31, 2008 with management and Deloitte & Touche LLP. The Audit Committee has discussed with Deloitte & Touche LLP the matters required to be discussed by Statement on Auditing Standards No. 114, The Auditor’s Communication with Those Charged with Governance, as adopted by the Public Company Accounting Oversight Board (“PCAOB”) in Rule 3200T. The Audit Committee has also received the written disclosures and the letter from Deloitte & Touche LLP required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the audit committee concerning independence, and has discussed with the independent accountants the independent accountants’ independence.
 
Based on its discussions with management and the independent registered public accounting firm, the Audit Committee has recommended to the Board of Directors that the audited consolidated financial statements be included in Power Integrations’ Annual Report on Form 10-K for the fiscal year ended December 31, 2008.

Description of 1998 Nonstatutory Stock Option Plan.  Our Board adopted the 1998 Nonstatutory Stock Option Plan, or the 1998 Plan, in July 1998. The 1998 Plan was approved by our directors; stockholder approval was not required at that time and was not sought. The 1998 Plan provided for the grant of nonstatutory stock options to our employees and consultants. There were initially 1,000,000 shares reserved under the 1998 Plan. No additional stock awards were granted under the 1998 Plan following stockholder approval of the 2007 Equity Incentive Plan, or the 2007 Plan, at the 2007 annual meeting of stockholders.
 
Our Board, or a committee appointed by our Board, set the terms of stock awards granted under the 1998 Plan subject to the terms of the 1998 Plan. The exercise price of nonstatutory stock options granted under the 1998 Plan is not less than 85% of the fair market value of the stock subject to the option on the date of grant. Options under the 1998 Plan generally terminate three months after termination of service for any reason other than death or disability, and six months after termination due to disability or death. The 1998 Plan shall continue in effect until the earlier of its termination by the Board or the date on which all of the shares of Stock available for issuance under the 1998 Plan have been issued and all restrictions on such shares under the terms of the 1998 Plan and the agreements evidencing Options granted under the 1998 Plan have lapsed. Stock awards generally vest over four years.

Section 16(A) Beneficial Ownership Reporting Compliance
 
Section 16(a) of the Securities Exchange Act of 1934 requires our executive officers, directors and persons who beneficially own more than 10% of our common stock to file initial reports of ownership and reports of changes in ownership with the SEC. These persons are required by SEC regulations to furnish us with copies of all Section 16(a) forms that they file.
 
Based solely on review of the forms furnished to us, we believe that all filing requirements applicable to the executive officers, directors and persons who beneficially own more than 10% of our common stock were complied with in 2008.
 
Compensation of Directors
 
Cash Compensation.  In 2007, each of our directors, with the exception of our one employee director, Balu Balakrishnan, received $5,000 per quarter to serve as a member of our Board. In addition, the chairman of our Audit Committee, Compensation Committee and Nominating and Governance Committee received $5,000, $1,875, and $1,250 per quarter, respectively, to serve as chairpersons of these committees. Our non-employee directors received compensation to attend board meetings via phone or in person of $750 and $1,500, respectively. The members of our Audit, Compensation and Nominating and Governance Committees received additional compensation for committee meeting attendance via phone or in person of $500 and $1,000, respectively. Non-employee directors were reimbursed for all reasonable travel and related expenses incurred in connection with attending Board and committee meetings.
 
These cash compensation arrangements continued in 2008 until revised by our Board on April 22, 2008. Effective April 1, 2008, each of our directors, with the exception of Mr. Balakrishnan, receives $6,000 per quarter to serve as a member of our Board, and the chairman of our Board receives an additional $6,250 per quarter to serve in such capacity. In addition, each chairman of our Audit Committee, Compensation Committee and Nominating and Governance Committee receives $5,000, $3,750, and $2,000 per quarter, respectively, for serving as chairpersons of these committees. Our non-employee directors receive compensation to attend Board meetings via phone or in person of $750 and $1,500, respectively. The members of our Audit, Compensation and Nominating and Governance Committees who are not the chairperson of the respective committee receive $2,000, $1,500 and $800 per quarter, respectively, to serve on these committees. Non-employee directors are reimbursed for all reasonable travel and related expenses incurred in connection with attending Board and committee meetings. In addition, on April 22, 2008, our Board approved a special one-time additional payment to Mr. Sharp calculated at $6,250 per quarter multiplied by the number of quarters beginning from the second quarter of fiscal 2006 (when he was elected chairman of our Board) through the first quarter of fiscal 2008.
 
Stock Option Awards.  Additionally, directors who are not employees of Power Integrations each receive equity compensation. In 2008, non-employee directors received stock options to purchase shares of common stock under the 1997 Outside Directors Stock Option Plan (the “Directors Plan”). The Directors Plan provides for the automatic grant of nonstatutory stock options to our non-employee directors over their period of service on the Board. The Directors Plan provides that each new non-employee director of Power Integrations will be granted an option to purchase 30,000 shares of common stock on the date on which such individual first becomes a non-employee director of Power Integrations (the “Initial Option”). Thereafter, each non-employee director who has served on the Board will receive an option to purchase 10,000 shares of our common stock, with such numbers of shares reduced pro rata if such non-employee director has served on the Board for less than one year (an “Annual Option”).
 
Initial Options to purchase 30,000 shares will continue to vest with respect to 1/3 of the shares on the first anniversary of the date of grant, and the remaining shares in a series of 24 successive equal monthly installments thereafter. Annual Options to purchase 10,000 shares will continue to be granted on the anniversary date of becoming a director for each of our directors who joined our Board after the date of our initial public offering, and for the others on the anniversary of our initial public offering each year. The Annual Options vest monthly over the 25th through 36th month following the date of grant.

Table of Contents

On January 27, 2009, the Directors Plan was amended to suspend the granting of Annual Options until December 31, 2009. Beginning in 2009, initial and annual grants are expected to be made to outside directors primarily under the Power Integrations 2007 Equity Incentive Plan (the “2007 Plan”) as follows (the “Directors Equity Compensation Program”):
 
  •  Under the Directors Equity Compensation Program, each current participant and each individual who would be eligible to participate in the Directors Plan would be a participant in the Directors Equity Compensation Program.
 
  •  The Directors Equity Compensation Program does not affect the vesting schedules or exercise prices of outstanding options held by non-employee directors.
 
  •  Pursuant to the Directors Equity Compensation Program, on the first trading day of July in each year (the “Regular Grant Date”), if a continuing eligible director (other than a new director) holds options pursuant to which 8,000 or more shares would vest during the period commencing with the 25th month and ending with the 36th month following the Regular Grant Date (the “Third Year”), he/she would not receive a new option grant under the 2007 Plan on that day.
 
  •  On the Regular Grant Date of each year, if a continuing eligible director (other than a new director) holds options pursuant to which less than 8,000 shares (or no shares) would vest during the Third Year, he/she would receive an option under the 2007 Plan to purchase 8,000 shares less the number of such shares. Such shares would vest monthly during the Third Year.
 
  •  Each of the Company’s outside directors has been granted, effective April 28, 2009, an option to purchase between 1,538 and 3,333 shares, such that the timing of vesting and the number of shares applicable to outside director options will be more uniform over the next three years.
 
  •  A new eligible director generally would receive under the 2007 Plan (or, if determined by the Committee, under the Directors Plan):
 
  (a)  On the first trading day of the month following commencement of service, an option to purchase the number of shares of common stock equal to: the fraction of a year (determined by reference to the number of months) between the date of the director’s appointment to the Board of Directors and the next July 1, multiplied by 8,000 (the number of shares of common stock subject to such option would be rounded down to the next whole share) and such shares would vest on such next July 1; and
 
  (b)  On the first trading day of July following commencement of service, an option to purchase 24,000 shares vesting monthly over the three year period commencing on the Regular Grant Date.
 
  •  The exercise price per share for the options to be granted under the Directors Equity Compensation Program is the fair market value of a share of Power Integrations’ Common Stock on the grant date as determined in accordance with the Option Agreements.
 
  •  The Directors Equity Compensation Program will remain in effect at the discretion of the Board or the Compensation Committee.
 
Compensation of Other Directors.  Mr. Balakrishnan, our chief executive officer and president, is not separately compensated for his services as a member of the Board.

Compensation of Executive Officers
 
Compensation Discussion and Analysis
 
The primary objectives of the Compensation Committee of the Board with respect to executive compensation are as follows:
 
1. To attract and retain qualified executive management
 
2. To fairly compensate executives for the value of work provided
 
3. To compensate executives for achieving specific company goals and objectives
 
4. To provide equity awards to executives so that each executive has a meaningful ownership interest in our company
 
5. To implement executive compensation programs in an objective and non-discriminatory manner.
 
To achieve these objectives, the Compensation Committee implements and maintains compensation plans that tie a substantial portion of the executives’ overall compensation to our company’s financial performance and the price of our common stock. Overall, an executive’s total compensation is intended to create an executive compensation program that is set at levels competitive with the executive compensation paid by other comparable public technology companies.
 
Role of our Chief Executive Officer in Determining Compensation.  The chief executive officer reviews with the Compensation Committee on a regular basis our compensation philosophy and programs, including with respect to the named executive officers, so that the Compensation Committee can recommend any changes necessary to keep our compensation philosophy and programs aligned with our business objectives. Mr. Balakrishnan, our chief executive officer, makes recommendations to the Compensation Committee with respect to the compensation of the named executive officers. The Compensation Committee also utilizes an outside compensation consultant to provide it with advice on competitive compensation plans. The Compensation Committee considers, but is not bound to and does not always accept, management’s and the outside consultant’s recommendations with respect to executive compensation. The Compensation Committee discusses Mr. Balakrishnan’s compensation with him, but deliberates and makes decisions with respect to Mr. Balakrishnan’s compensation without him present.
 
Mr. Balakrishnan and other executive officers attend some of the Compensation Committee’s meetings, but leave the meetings as appropriate when matters of executive compensation specific to them are discussed.
 
Comparative Compensation Analysis and Role of Compensation Consultant.  Power Integrations aligns both its cash and equity compensation to market comparables. The Compensation Committee selects peer companies on the basis of fiscal and business similarities to Power Integrations. The Compensation Committee analyzes market compensation practices annually using the most directly relevant published survey sources available, including surveys from Radford + Consulting (“Radford”) and Culpepper and Associates, Inc. which were used for the 2007 and 2008 compensation analyses. The Compensation Committee considered peer companies using several screening factors: (1) annual revenues in excess of $75 million; (2) similarities among global scope and complexity of the company’s business; and (3) inclusion in industry-specific categories of semiconductors and related services, integrated circuits, semiconductor solutions and computer communications. The peer group that results from this screening method is large and diverse enough that the addition or elimination of any one company

will not alter the overall analysis. Under this approach, the peer group used by the Compensation Committee during fiscal year 2008 was the same as fiscal year 2007. The full list of twenty (20) companies is as follows:

In 2006, the Compensation Committee engaged an independent compensation consulting firm, Meyercord & Associates, Inc. (“Meyercord”), to assist in the analysis of compensation survey data. Meyercord has consistently been engaged by the Compensation Committee through 2007 and 2008. Meyercord attends Compensation Committee meetings from time to time and provides peer group analysis, feedback and recommendations to the Compensation Committee. In addition to survey data, the Compensation Committee analyzes information reported in peer companies’ SEC filings for all elements of compensation, including salary, cash incentive compensation, and equity compensation.
 
Timing of Equity Awards.  Subject to business needs, our policy is to grant option awards to new employees on the first trading day of the month following the date of hire, and annually to grant continuing employees option awards on the third trading day following the earnings release for the first fiscal quarter of each year. All option grants are set at the closing price on the day of the grant.
 
The Compensation Committee is not bound by award formulas and is free to exercise its discretion to adjust cash bonus awards and equity awards.
 
Executive Compensation Components
 
Executive compensation is divided into the following components:
 
Base Salary.  The Compensation Committee establishes base salaries for our executives based on the scope of their responsibilities, taking into account competitive market compensation paid by other companies for similar positions. Generally, the Compensation Committee believes that executive base salaries should be targeted at or


24


Table of Contents

above the 50th percentile of salaries for executives in similar positions and with similar responsibilities at peer companies in order to attract and retain qualified executives. The Compensation Committee generally reviews base salaries annually, and adjusts them from time to time to realign salaries with market levels after taking into account individual responsibilities, performance and experience. The 2006, 2007 and 2008 salaries of each of the named executive officers are set forth in the table below entitled “Summary Compensation Table.”
 
Annual Bonus.  The Compensation Committee believes that a substantial portion of the annual compensation for each executive officer should be in the form of variable incentive bonuses and our policy is to target annual incentive bonuses at or above the 50th percentile of peer companies.
 
This resulted in 2008 cash bonus compensation targets to be 69% of annual salary for our chief executive officer and approximately 39% of annual salary for other named executive officers. The Compensation Committee established this policy and these targets in order to attract qualified executives, align their interests with those of our stockholders, and provide appropriate executive and leadership incentives. Generally, the Compensation Committee aligns an executive’s annual target bonus with the target bonuses of executives with similar positions in comparable companies. The annual incentive bonuses are intended to compensate officers for achieving annual financial goals at the corporate level. For 2008, the Compensation Committee determined that actual bonus payments would be based upon revenue, and non-GAAP operating income performance, as described below. The Compensation Committee made this decision to emphasize revenue growth and to focus management on operating performance by excluding the impact of changes in interest rates, tax rates and share count on income. The 2008 target bonuses for each of the named executive officers are set forth in the table below entitled “Grants of Plan-Based Awards in 2008.”
 
2008 Executive Officer Bonus Plan.  Each officer, as described below, was assigned a 2008 target bonus using the criteria described above. Bonuses were earned based on company performance against the established revenue targets and non-GAAP operating income targets of the 2008 Executive Officer Bonus Plan (the “2008 Plan”). The operating income targets were based on non-GAAP operating income, which excluded certain expenses, including (a) SFAS 123(R) charges, (b) specified legal fees and settlements, and (c) any settlements with the Internal Revenue Service. These items were excluded because the Compensation Committee reasoned that these items were not indicative of our core operating performance and did not relate to achieving the compensation objectives as discussed above.
 
Weighting of the target components was as follows:
 
         
Revenue
    25 %
Non-GAAP Operating Income
    75 %
Total
    100 %
 
Revenue Component of Executive’s Bonus:  No pay out was made under the 2008 Plan as actual revenue did not exceed $210 million, the established minimum amount of revenue as set forth in the 2008 Plan. If 2008 actual revenue had increased above the minimum amount of revenue, the actual bonus would have increased, up to 100% of the revenue component of the target bonus when actual revenue equaled target revenue of $225 million in the 2008 Plan, and the bonus would have continued to increase thereafter as actual revenue increased, up to a maximum of 200% of the revenue component of the target bonus when revenues reached $240 million.
 
Operating Income Component of Executive’s Bonus:  No pay out was made under the 2008 Plan as actual non-GAAP operating income did not exceed $45.0 million, the established minimum amount of non-GAAP operating income as set forth in the 2008 Plan. If 2008 actual non-GAAP operating income had increased above the minimum amount of non-GAAP operating income, the actual bonus would have increased, up to 100% of the non-GAAP operating income component of the target bonus when actual non-GAAP operating income equaled target non-GAAP operating income of $53.4 million in the 2008 Plan, and the bonus would have continued to increase thereafter as actual non-GAAP operating income increased, up to a maximum of 200% of the non-GAAP operating income component of the target bonus when non-GAAP operating income reached $61.7 million.
 
Long-Term Equity-Based Incentive Awards.  The goal of Power Integrations’ long-term, equity-based incentive awards is to align the interests of executive officers with stockholders and to provide each executive officer with an incentive to manage Power Integrations from the perspective of an owner with an equity stake in the

business. We further believe that long-term performance is achieved through a culture that encourages long-term performance by our executive officers through the use of stock-based awards. We believe that having a meaningful potential financial gain through the company stock option plan assists us in retaining our executive officers and helps align their financial interests with our stockholders’ interests. The Compensation Committee has not set stock ownership guidelines for executives because in some cases, guidelines would place a financial burden on the executive. The Compensation Committee considers the available shares for distribution and determines the size of the grants of equity-based incentives according to several factors, including market survey data of peer companies, the executive’s past performance and expected future contribution, the retention value of the executive’s prior unvested option grants, Power Integrations’ growth and performance outlook, and the option grants provided to executives in similar positions at comparable companies. The Compensation Committee does not believe the accounting treatment of the various types of equity awards should be the primary basis for making equity award decisions and instead primarily bases its decisions on executive and company performance and the practice of competitor companies.
 
During 2008, the Compensation Committee made option grants to Power Integrations’ executive officers as indicated in the “Grants of Plan-Based Awards in 2008” table below. Each grant allows the executive officer to acquire shares of Power Integrations’ common stock at a fixed price per share. The option grant will provide a return only if Power Integrations’ common stock appreciates over the option term. At the executive level, there is the greatest emphasis on linking pay to performance to align the interests of the executives directly with the stockholders. The level of grants were determined based on peer companies’ equity usage rates and equity compensation attributes. Specifically, the Committee considered the number of shares granted at peer companies, the relative value of other company shares and the value of the shares relative to the total compensation of each executive.
 
On December 31, 2008, Power Integrations completed a tender offer to exchange for cash certain outstanding “out of the money” stock options to purchase shares of Power Integrations’ common stock. Each eligible optionee who validly tendered eligible options received a cash payment in the amount of $2.00 per share for options granted in 2004 or 2005, and $4.00 per share for options granted in 2006, 2007 or 2008 (before September 15, 2008). To reduce our stock compensation expenses and to help retain and to reward Power Integrations’ valued executive officers for their services and contributions to Power Integrations, the executive officers were allowed to participate in the tender offer along with Power Integrations’ other employees.
 
Other Compensation.  Our executives are party to employment agreements and offer letters (“Employment Agreements”) that contain provisions regarding severance benefits in the event the executive is terminated without cause or is terminated in connection with a change in control. These benefits include continued health plan coverage and extended time to exercise stock options in the event of termination of employment upon a change of control or after a set age following an extended amount of service to our company and accelerated vesting of stock options. The Compensation Committee approved these employment agreements because it believes these severance provisions are necessary to retain our current executives and to attract future executives. These severance benefits are coupled with non-competition and non-solicitation obligations intended to protect our proprietary data that might not be enforceable in the absence of additional consideration. The severance benefits are also intended to motivate named executive officers to continue employment with the company and maximize stockholder value in the event of a potential change in control. A summary of the material terms of these Employment Agreements, together with a quantification of the benefits available under the agreements, may be found in the section below entitled “Summary of Executive Compensation — Employment Contracts and Termination of Employment and Change of Control Agreements.”
 
Perquisites and Generally Available Benefit Programs
 
We annually review the perquisites that named executive officers receive. Our named executive officers, like our other employees, are eligible to participate in our employee stock purchase plan. However, any employee who is a stockholder of more than 5% of our voting stock is not eligible to participate in the employee stock purchase plan. In addition, the named executive officers may participate in the various employee benefit plans that are generally available to all employees, including medical, vision and dental care plans; flexible spending accounts for healthcare; life, accidental death and dismemberment and disability insurance; and paid time off.

We also maintain a 401(k) retirement savings plan for the benefit of all of our employees, including our named executive officers. For fiscal 2008, Power Integrations did not match employee contributions to the 401(k) plan (if financial results reached certain thresholds the plan provides matching up to $3,000 for each U.S. employee). We do not provide specified retirement programs such as pension plans, or deferred compensation plans. We provide certain retirement benefits to the named executive officers, as described below under the heading “Pension Benefits.”
 
Federal Tax Considerations
 
Section 162(m) of the Internal Revenue Code of 1986, as amended, limits Power Integrations to a deduction for federal income tax purposes of no more than $1 million of compensation paid to certain named executive officers in a taxable year. Compensation above $1 million may be deducted if it is “performance-based compensation” within the meaning of the Internal Revenue Code. For 2008, no executive was paid more than $1 million. To date, the tax effects of Internal Revenue Code Section 162(m) have not been a material factor in establishing appropriate executive compensation.
 
2009 Executive Compensation Actions
 
On March 9, 2009, the Compensation Committee approved, consistent with the compensation philosophy and goals described above, the following salary and bonus plan (the “2009 Bonus Plan”).
 
2009 Salaries and Target Bonuses

  Vice President, Sales   $ 265,000       4,000  
Derek Bell
  Vice President, Engineering   $ 275,000       4,000  
 
The salaries for 2009 remained unchanged from 2008. The Compensation Committee determined that salaries should not be changed from 2008 levels both due to the performance of the company, and as a result of the current economic climate.
 
The Compensation Committee determined that bonuses would be paid in restricted stock units, rather than in cash, for 2009. The Compensation Committee determined to employ the use of restricted stock units as opposed to cash to reduce cash expenses and because it believed restricted stock units would generate stronger incentives to align performance with a higher price in Power Integrations’ common stock. As share price increases, the executives see an increase in the value of their bonus thus linking the interests of the executives directly with those of the stockholders. The Compensation Committee set the number of restricted stock units, consistent with its decision to keep 2009 salaries constant, to provide the same economic equivalent target bonus as 2008 target cash bonus assuming a stock price of $27.00 per share. This per share value was chosen based upon the historical trading price of Power Integrations’ common stock.
 
2009 Bonus Plan
 
As with the 2008 Plan, for the 2009 Bonus Plan, the Compensation Committee aligned the executive’s annual target bonus with the target bonuses of executives with similar positions in comparable companies. The Committee generally does not consider the effect of past changes of stock price, expected bonus payouts or earnings under past plans in setting future awards of executive officers. In addition, incentive compensation decisions are made without regard to length of service or prior awards. In 2009, the Compensation Committee attempted to target the annual incentive bonuses at or above the 50th percentile of peer companies assuming the stock returned to 2008 levels.
 
Bonuses, which will be awarded in restricted stock units, will be earned based on company performance as against the 2009 Bonus Plan’s established revenue targets and non-GAAP operating income targets. The non-


27


Table of Contents

GAAP operating income targets were based on non-GAAP operating income, which excluded certain expenses, including (a) FAS 123R expense and (b) any extraordinary income and or expenses associated with mergers and acquisition activities, patent lawsuit settlements and IRS settlements. These items were excluded because the Compensation Committee reasoned that these items were not indicative of operating performance and did not relate to achieving Power Integrations’ compensation objectives. Weighting of the target components, consistent with the 2008 bonus plan, is 25% on revenue, and 75% on non-GAAP operating income.
 
We believe these metrics are directly tied to our core operating performance, are key factors in driving stockholder value, and are important business elements that our executives can meaningfully influence. By focusing on these metrics, we seek to align the financial interests of our executives with those of our stockholders.
 
Revenue Component of Executive’s Bonus:
 
No pay out will be made under the 2009 Bonus Plan if the company’s 2009 actual revenue does not exceed at least an established minimum amount of revenue as set forth in the 2009 Bonus Plan. To the extent 2009 actual revenue increases above the minimum amount of revenue, the actual bonus increases, up to 100% of the revenue component of the target bonus when actual revenue equals target revenue in the 2009 Bonus Plan, and continues increasing thereafter at a slower rate as actual revenue increases, up to a maximum of 200% of the revenue component of the target bonus.
 
Non-GAAP Operating Income Component of Executive’s Bonus:
 
No pay out will be made under the 2009 Bonus Plan if the company’s 2009 actual non-GAAP operating income does not exceed at least an established minimum amount of non-GAAP operating income as set forth in the 2009 Bonus Plan. To the extent 2009 actual non-GAAP operating income increases above the minimum amount of non-GAAP operating income, the actual bonus increases, up to 100% of the non-GAAP operating income component of the target bonus when actual non-GAAP operating income equals target non-GAAP operating income in the 2009 Bonus Plan, and continues increasing thereafter at a slower rate as actual non-GAAP operating income increases, up to a maximum of 200% of the non-GAAP operating income component of the target bonus.
 
Non-GAAP Operating Income and Revenue Targets
 
The specific revenue and non-GAAP operating income numbers used with regard to the targets involve confidential trade secrets or confidential commercial or financial information, the disclosure of which would result in competitive harm to Power Integrations.
 
At the time that these goals were set by the Compensation Committee, they were substantially uncertain to be achieved. The Compensation Committee believes that the threshold-level targets cannot be achieved easily, especially in light of the current economic environment. The Compensation Committee set these levels, with the advice of its compensation consultant, with difficulty in attainment levels consistent with 2008; in 2008 the threshold-level targets for non-GAAP operating income and revenue were not achieved. The target and maximum targets represent increasingly challenging and aggressive levels of performance. The Compensation Committee believed that reaching the target levels for these goals would have been unlikely without substantial growth of existing business and new business resulting in market share gains.
 
Compensation “Claw-back”
 
In 2009, pursuant to our litigation settlement, we also implemented a compensation “claw-back” mechanism with respect to our compensation of our executive officers that conditions the earning and payment of any cash or stock bonuses to executive officers on an agreement to repay a portion of such bonuses in the event of a restatement resulting from intentional misconduct by such officers. Specifically, in the event of intentional misconduct that results in an accounting restatement of any financial statement filed in the twelve (12) months prior to the payout of the bonus due to material noncompliance by the company with any financial reporting requirements of the federal securities laws, the officers determined by the Board to have engaged in such intentional misconduct will reimburse the company the difference between the amount of any bonus received that was based on the original financial statements and the amount of the bonus such officer would have received had the amount of the bonus been calculated based on the restated financial statements.

(1) Reflects the date the Compensation Committee determined to make the grant, such grant to be effective on the grant date designated in the column to the left, at the fair market value on the grant date. Grant dates were designated at the time of the Compensation Committee’s action, which dates were dates on which the company was not in possession of material, non-public information, e.g., the third trading day after release of earnings.
 
(2) These columns set forth the threshold, target and maximum amounts of each named executive officer’s annual cash bonus award for the year ended December 31, 2008 under our annual cash bonus award program. The actual cash bonus awards earned for the year ended December 31, 2008 for each named executive officer are set forth in the “2008 Summary Compensation Table” above. As such, the amounts set forth in these columns do not represent additional compensation earned by the named executive officers for the year ended December 31, 2008. For a description of our annual cash bonus award program, see “Compensation Discussion and Analysis.”
 
(3) No pay out would be made if Power Integrations’ 2008 actual revenue and actual non-GAAP operating income did not exceed at least an established minimum amount as set forth in the 2008 Executive Officer Bonus Plan. Since Power Integrations’ 2008 actual revenue and actual non-GAAP operating income did not exceed such established minimum amounts, no pay out for fiscal year 2008 was made.
 
(4) Target represents the amount earned if the metrics in the 2008 Executive Officer Bonus Plan were fully met.
 
(5) Maximum represents the maximum payout under the program, which is 200% of target.
 
(6) Stock options were granted pursuant to the 2007 Equity Incentive Plan and were immediately exercisable. Six months from the date of grant, 1/8 of the shares subject to the stock option vest, with the remainder vesting monthly over the subsequent 42 months subject to the optionee’s continued employment or service with Power Integrations. Power Integrations has a right to repurchase shares issued upon the exercise of unvested options until such shares become vested. Under the terms of the 2007 Equity Incentive Plan, the administrator retains the discretion, subject to the 2007 Equity Incentive Plan limits, to amend the terms of outstanding options. The options generally have a maximum term of 10 years, subject to earlier termination in certain situations related to cessation of employment or service.
 
(7) Represents the grant date fair value of such option award as determined in accordance with SFAS No. 123(R). These amounts have been calculated in accordance with SFAS No. 123(R) using the Black-Scholes-Merton valuation model.

(1) Except as described in footnote (2) below, options in this table were granted from the 1997 Stock Option Plan and are immediately exercisable and vest fully within four years from the grant date subject to the optionee’s continued employment or service with Power Integrations. Such options vest at the rate of 1/8 on the six-month anniversary of the date of grant and 1/48 monthly thereafter. Power Integrations has a right to repurchase shares issued upon the exercise of unvested options until such shares become vested. Under the terms of the 1997 Stock Option Plan, the administrator retains the discretion, subject to the 1997 Stock Option Plan limits, to modify the terms of outstanding options and to reprice outstanding options. The options generally have a maximum term of 10 years, subject to earlier termination in certain situations related to cessation of employment or service.
 
(2) In 2006, our named executive officers voluntarily amended a number of the stock options held by them to provide that they were only exercisable during a specified calendar year. This is one of the options that were so amended.

Employment, Severance and Change of Control Agreements
 
Executive Officer Benefits Agreement.  On April 25, 2002, Power Integrations entered into a chief executive officer benefits agreement with Balu Balakrishnan. The form of the agreement was approved by the Compensation Committee on April 18, 2002 and amended by the Compensation Committee on August 8, 2007 (the “CEO Benefits Agreement”). On August 8, 2007, Power Integrations entered into amended and restated executive officer benefits agreements with its named executive officers Derek Bell, vice president, engineering, John Tomlin, vice president, operations and Bruce Renouard, vice president, sales. In addition, as of August 8, 2007, Power Integrations entered into an executive officer benefits agreement with Rafael Torres, Power Integrations’ then chief financial officer. On November 5, 2008, Power Integrations entered into an executive officer benefits agreement with its current chief financial officer, Bill Roeschlein. The executive officers benefits agreements referenced in this paragraph, including the CEO Benefits Agreement, as amended as the case may be, are referred to as the “Executive Officer Benefits Agreements,” and the executive officers referred to in this paragraph, are referred to as the “Officers.”
 
The Executive Officer Benefits Agreements, as amended as the case may be, provide for certain benefits, as described below, including:
 
  •  acceleration of vesting of stock options upon a change of control of Power Integrations,
 
  •  severance benefits in the event of termination of employment by Power Integrations without cause or resignation by the Officer for good reason within 18 months after a change of control,
 
  •  severance benefits in the event of termination of employment by Power Integrations without cause or resignation by the Officer for good reason, and
 
  •  retirement benefits.
 
A change of control is defined in the Executive Officer Benefits Agreements as an acquisition by any person of a beneficial ownership of 50% or more of Power Integrations’ voting stock or outstanding shares of common stock, certain mergers or other business combinations involving Power Integrations, the sale of more than 50% of Power Integrations’ assets, liquidation of Power Integrations, or a change in the majority of the incumbent members of the Board within a two-year period (except changes in the Board’s composition approved by a majority of the directors). “Cause” includes, among other acts, a material act of theft, dishonesty, fraud, falsification of records, improper disclosure of confidential information, or an intentional act by the Officer causing harm to the reputation of Power Integrations, and “good reason” includes, among other acts, a material decrease in the Officer’s compensation or benefits following a change of control, a demotion or material reduction in responsibility level, or relocation of more than 50 miles from the Officer’s current work place or a material adverse change in working conditions or established working hours which persist for a period of six months.
 
Upon a change of control, 50% of Mr. Balakrishnan’s then-unvested shares will vest, but if an acquiring company does not assume the options, 100% of Mr. Balakrishnan’s then-unvested shares will vest. With respect to the other Officers, upon a change of control, 25% of the Officer’s then-unvested shares will vest. However, if an acquiring company does not assume the options, 50% of the Officer’s then-unvested shares will vest if the Officer is a “new executive” (an executive with fewer than five years of service to Power Integrations as an executive officer) and 100% of the Officer’s then-unvested shares will vest if the Officer is a “senior executive” (an executive with at least five years of continuous service to Power Integrations as an executive officer). Mr. Bell, Mr. Renouard and Mr. Tomlin are senior executives and Mr. Roeschlein is a new executive. Mr. Torres is no longer with the company, and was a new executive during his tenure at the company.
 
Pursuant to the Executive Officer Benefits Agreements, new executives are first eligible for the benefits under such agreements upon completion of one year of continuous service as an executive officer of Power Integrations, unless the Board of Directors or the Compensation Committee determines otherwise. On October 21, 2008, the Compensation Committee permitted Mr. Roeschlein to benefit from the change of control provisions of his Executive Officer Benefits Agreement during the first year of continuous service to the company as an executive officer. Mr. Roeschlein will not benefit from the other provisions of his Executive Officer Benefits Agreement until completion of one year of continuous service as an executive officer of Power Integrations. Thus, to the extent the


35

provisions described in this section do not relate to a change of control, they apply to Mr. Roeschlein starting on June 30, 2009.
 
Mr. Balakrishnan is entitled to severance benefits in the event that he is terminated without cause or he resigns for good reason within 18 months after a change of control. These severance benefits include a lump-sum cash payment equal to twelve months of his highest annual salary from Power Integrations plus targeted annual incentive bonus, acceleration of 100% of all his then-outstanding stock options, extension of the post-termination stock option exercise period to one year, and continued medical and dental coverage under the Power Integrations health plans for twelve months at Power Integrations’ expense.
 
Each Officer other than Mr. Balakrishnan is entitled to severance benefits in the event that he is terminated without “cause” or he resigns for “good reason” within 18 months after (i) a change of control or (ii) the date that Mr. Balakrishnan ceases to serve as chief executive officer. These severance benefits include a lump-sum cash payment equal to six months of the Officer’s highest annual salary from Power Integrations plus 50% of the Officer’s targeted annual incentive bonus (and for a senior executive, up to an additional six months of salary and 50% of bonus until such senior executive secures new employment, paid on a ratable monthly basis), vesting of 50% of then-unvested shares if the Officer is a new executive, or vesting of 100% of then unvested shares if the Officer is a senior executive, extension of the post-termination stock option exercise period to one year for vested options, and continued medical and dental coverage under the Power Integrations’ health plans at Power Integrations’ expense for up to six months if the Officer is a new executive, or for up to twelve months if the Officer is a senior executive.
 
In addition, each Officer is entitled to severance benefits in the event of termination of employment by Power Integrations without cause or resignation by such Officer for good reason. Such severance benefits include a lump-sum cash payment equal to six months (twelve months in the case of Mr. Balakrishnan) of the Officer’s highest annual salary plus 50% (100% in the case of Mr. Balakrishnan) of the Officer’s targeted annual incentive bonus, and continued medical and dental coverage under the Power Integrations’ health plans for six months (twelve months in the case of Mr. Balakrishnan) at Power Integrations’ expense. In addition, Mr. Balakrishnan is entitled to vesting acceleration of 50% of all his then-unvested stock options.
 
Each Officer is entitled to retirement benefits if he has served Power Integrations for 15 years and has achieved an age of 50, or has served Power Integrations for 10 years and has achieved an age of 55, is not employed elsewhere, full time (other than for an organization described in section 501(c)(3) of the Internal Revenue Code of 1986, as amended), or otherwise engaged in “Competition” (as defined in the Executive Officer Benefits Agreement) with Power Integrations, and does not recruit or employ any present or future employee of Power Integrations. The Officer is entitled to the extension of his post-termination stock option exercise period for vested options for the term of the option (not to exceed five years in the case of Officers other than Mr. Balakrishnan) and medical and dental benefits for him and his dependents at Power Integrations’ expense until he achieves the age of 65; thereafter, participation in the health plans would be at the Officer’s expense. Power Integrations will use commercially reasonable efforts to provide that the Officer will continue to be eligible for coverage under Power Integrations’ medical and dental plans upon retirement. These retirement benefits will also become available if an Officer was eligible for such benefits and his employment terminates due to death or disability.
 
The post-termination exercise period for an Officer’s vested stock options granted prior to April 26, 2002 will be extended only if such extension does not require Power Integrations to incur a compensation expense for financial statement purposes.
 
If any of the payments and benefits provided under the Executive Officer Benefits Agreements in connection with a change of control (the “Payments”) would result in a “parachute payment” under Section 280G of the Internal Revenue Code of 1986, as amended, the amount of such Payments will be either (i) the full amount of the Payments or (ii) a reduced amount which would result in no portion of the Payments being subject to excise tax (as defined in the Executive Officer Benefits Agreements, as amended), whichever amount provides the greatest amount of benefit to the Officer.
 
Mr. Torres, Power Integrations’ former chief financial officer, ceased employment with Power Integrations on July 21, 2008. Pursuant to his Transition and Separation Agreement, dated July 23, 2008 and in exchange for a release of claims, Mr. Torres received severance benefits, including: (i) six (6) months base salary in effect as of


36

July 21, 2008, (ii) his targeted 2008 annual incentive bonus (prorated to July 21, 2008) and (iii) fifty percent (50%) of his targeted 2008 annual incentive bonus.
 
Pension Benefits

(1) Mr. Roeschlein is not eligible for any benefits under his Executive Officer Benefits Agreement other than those relating to change of control until completion of one year of continuous service at Power Integrations.
 
(2) Mr. Torres left employment of Power Integrations in July 2008, and was not eligible for pension benefits at December 31, 2008.
 
Only Mr. Balakrishnan is currently eligible to receive medical benefits upon retirement. For the other named executive officers, they will become eligible upon the earlier to occur of (a) age 50 with 15 years of service or (b) age 55 with 10 years of service. The valuation method and all material assumptions are as follows: The amounts determined in the above table are associated with the provision of health care coverage after retirement. The valuation method is pursuant to the Financial Accounting Standards Board’s Statement of Financial Accounting Standards No. 106, Employers’ Accounting for Postretirement Benefits Other Than Pensions. The Projected Unit Credit attribution method was used; the attribution of the obligation is over the period from hire to benefit eligibility (the earlier of age 50 with 15 years of service or age 55 with 10 years of service). Other than for eligibility purposes, service is not considered in the calculation. The benefit consists of health care coverage from retirement until age 65. The basis for the benefit is premiums paid by the employer to a third-party insurer, without additional subsidy imputed. The obligations were calculated using the following assumptions:
 
  •  The discount rate for future payments was 5.50% as of 12/31/2008.
 
  •  The assumed annual increase in health care costs is 10% as of 12/31/2008, with the annual increase lessening by 1/2% per year, to an ultimate rate of 5% in 2019.
 
  •  25% of active participants are assumed to become eligible and elect coverage at retirement.
 
  •  Retirement is assumed to take place at age 62, or at first eligibility if older.
 
  •  2/3 of active employees are assumed to have eligible spouses who, at the employee’s retirement, will be covered by the plan. Husbands are assumed to be three years older than their wives.

Potential Payments upon Retirement or Change of Control
 
The following table provides information concerning the estimated payments and benefits that would be provided in each of the circumstances described above. Payments and benefits are estimated assuming that the triggering event took place on the last business day of fiscal 2008 (December 31, 2008), and the price per share of Power Integrations’ common stock is the closing price on the Nasdaq Global Select Market as of that date ($19.88). There can be no assurance that a triggering event would produce the same or similar results as those estimated below if such event occurs on any other date or at any other price, of if any other assumption used to estimate potential payments and benefits is not correct. Due to the number of factors that affect the nature and amount of any potential payments or benefits, any actual payments and benefits may be different. The information presented below assumes no adjustment of the payment of benefits to help avoid excise tax under Section 409A of the Internal Revenue Code of 1986, as amended.

(2) For termination within 18 months of a change in control (which, for these purposes for executive officers other than Mr. Balakrishnan, includes Mr. Balakrishnan ceasing to be our chief executive officer) other than for cause or voluntary termination for good reason: with respect to Mr. Balakrishnan twelve months salary plus his targeted annual bonus, 100% acceleration of all his then-unvested options, and twelve months medical and dental coverage; for all others, six months salary plus 50% of targeted bonus, 100% of unvested options would vest upon a change of control for senior executives and 50% of unvested options would vest upon change of control for new executives, and 12 months medical and dental coverage for senior executives and six months medical and dental coverage for new executives. If executive is a senior executive, payment up to an additional six months salary and 50% bonus will be paid in ratable monthly installments until the executive secures new employment. The amounts set forth in the table assume that the senior executives will not secure new employment.
 
(3) Reflects benefits in the event of a change of control in which the acquiring company assumes outstanding options. With respect to Mr. Balakrishnan 50% of all his then-unvested options would vest; for all others, 25% of the unvested options would vest.
 
(4) Reflects benefits in the event of a change of control in which the acquiring company did not assume outstanding options. With respect to Mr. Balakrishnan 100% of all his then-unvested options would vest; for all others, 50% of the unvested options would vest for a new executive and 100% for a senior executive.
 
(5) Reflects the aggregate market value of unvested option grants. For unvested option grants, aggregate market value is computed by multiplying (i) the difference between $19.88, the closing price per share on the Nasdaq

Table of Contents

Global Select Market at December 31, 2008, and the exercise price of the option, by (ii) the number of shares underlying unvested options at December 31, 2008.
 
(6) Reflects the aggregate market value of extensions of stock option exercise periods. The post-termination exercise period for an Officer’s vested stock options granted prior to April 26, 2002 will be extended only if such extension does not require Power Integrations to incur a compensation expense for financial statement purposes. Mr. Balakrishnan is eligible for an extension of his stock option exercise period for vested options to one year upon termination within 18 months of a change in control, or for the term of the option in the case of retirement. Officers, other than Mr. Balakrishnan, are eligible for an extension of their stock option exercise periods to one year upon a termination within 18 months of a change of control, and up to five years upon retirement (assuming such Officers are eligible to receive retirement benefits). The values of the extensions of the stock option exercise periods are computed by using the Black-Scholes-Merton model in accordance with SFAS No. 123(R) and calculating the difference between (i) the fair value of each applicable option with the extended option expiration date minus (ii) the fair value of each applicable option with the original option expiration date.
 
(7) For retirement, upon completion of service and age requirements, health coverage is paid until the age of 65. For severance, reflects the cost of health coverage (COBRA) to maintain the benefits currently provided. Calculated based upon the rates at December 31, 2008.
 
(8) The total termination benefits received by the Officer for termination within 18 months of a change of control may be lower than what is stated in this table in light of a provision in the Officers’ respective Executive Officers Benefits Agreement which states that if any of the payments and benefits provided under such agreements (the “Payments”) in connection with a change of control would result in a “parachute payment” under Section 280G of the Internal Revenue Code, the amount of such Payments will be either (i) the full amount of the Payments or (ii) a reduced amount which would result in no portion of the Payments being subject to excise tax (as defined in the respective agreements), whichever amount provides the greatest amount of benefit to the Officer.
 
COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION
 
In 2008, Power Integrations’ Compensation Committee consisted of Mr. Sharp, Mr. Kvamme and Mr. Brown. On January 27, 2009, as a result of the passing of Mr. Brown, Mr. Bickell was appointed to the Compensation Committee. None of the current members of the Compensation Committee nor Mr. Brown is or was an officer or employee of Power Integrations or its subsidiaries except for Mr. Sharp, who served as the chief executive officer of Power Integrations during its first year in 1988. None of Power Integrations’ executive officers serves as a member of the board of directors or compensation committee of any entity that has one or more executive officers serving as a member of Power Integrations’ Board or Compensation Committee.
 
CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS
 
Related Party Transactions We did not conduct any transactions with related persons in fiscal 2008 that would require disclosure in this proxy or approval by the Audit Committee or another independent body of the Board.
 
Related Party Transactions Policies and Procedures Our policy, included in our Code of Business Conduct and Ethics, is that all directors, officers, and employees must avoid any activity that is or appears to conflict with the interests of Power Integrations. Our directors, officers, and employees are aware of the applicable provisions of our Code of Business Conduct and Ethics, and we become aware of related party transactions through periodic reviews by, and notifications to, management, including the completion of an annual Director and Officer questionnaire. We conduct a review of all related party transactions for potential conflict of interest. Any potential conflicts of interest must be reviewed and ratified, if applicable, by the Audit Committee and or another independent body of our Board. During fiscal 2008, we did not have any related party transactions requiring review, nor did we have any transactions where the policy and procedure were not followed.
 
HOUSEHOLDING OF PROXY MATERIALS
 
The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for Notices of Internet Availability of Proxy Materials and Annual Meeting materials with respect to two or more stockholders sharing the same address by delivering a single Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials addressed to those stockholders. This process, which is commonly

referred to as “householding,” potentially means extra convenience for stockholders, allows us to save money by reducing the number of documents we must print and mail and helps protect the environment as well.
 
Householding is available to both registered stockholders (i.e., those stockholders with certificates registered in their name) and street name holders (i.e., those stockholders who hold their shares through a brokerage).
 
If you are a registered stockholder and have consented to our mailing of proxy materials and other stockholder information only to one account in your household, as identified by you, we will deliver or mail a single copy of our Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, for all registered stockholders residing at the same address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding,” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, please notify your broker or direct your written request to Investor Relations Department, Power Integrations, Inc., 5245 Hellyer Avenue, San Jose, California 95138-1002, or contact Investor Relations Department at 408-414-8528. A separate copy of a Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials will then promptly be delivered to you. Stockholders who currently receive multiple copies of the Notice of Internet Availability of Proxy Materials or set of Annual Meeting materials, as applicable, at their address and would like to request “householding” of their communications should contact their brokers.
 
OTHER MATTERS
 
The Board knows of no other matters that will be presented for consideration at the annual meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.
