Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On June 25, 2009, the Compensation Committee of the Board of Directors of Volterra Semiconductor Corporation (the "Company") approved increases to base salaries of certain executive officers as described below. These increases were based on peer data collected by the Company's independent compensation consultant early in January 2009, but no actions or approvals were sought at that time in light of a Company-wide salary freeze placed into effect as a result of business uncertainties affecting the worldwide economy.
With improvements in business conditions, the Company recently lifted its salary freeze and the Committee approved salary increases for Mr. Mike Burns and Dr. David Lidsky, based on their responsibilities and performance and in line with our peer group data. Based on this data, no changes were proposed for the base salaries of Mr. Jeff Staszak, Mr. Bill Numann or Dr. Craig Teuscher. The salary changes will take effect on July 1, 2009.
