EL SEGUNDO, Calif.—May, 2012 — Efficient Power Conversion Corporation (EPC) CEO Alex Lidow will speak at the private Credit Suisse investor conference in San Francisco on Tuesday, May 22, at 10:00 a.m. Pacific time. Dr. Lidow will discuss the growing market for gallium nitride transistors with a focus on EPC’s eGaN® FET technology and products. As a displacement technology, GaN FETs can be used in an array of current MOSFET applications in addition to enabling new high volume applications, such as wireless power and envelope tracking, a method for significant energy savings in communication devices.

Following the presentation, it will be archived for viewing on the EPC website (www-epc-co.com).

About EPC

EPC is the leader in enhancement mode gallium nitride based power management devices. EPC was the first to introduce enhancement-mode gallium-nitride-on-silicon (eGaN) FETs as power MOSFET replacements in applications such as servers, wireless power transmission, envelope tracking, RF transmission, power-over-ethernet (PoE), solar micro inverters, energy efficient lighting, and class-D audio amplifiers with device performance many times greater than the best silicon power MOSFETs.
