EL SEGUNDO, Calif.--(BUSINESS WIRE)—Efficient Power Conversion Corporation (EPC) today announced the introduction of the EPC9002 development board to make it easier for users to get started designing with EPC’s 100V enhancement-mode GaN transistor products.

The EPC9002 development board is a 50 V maximum input voltage, 7 A maximum output current, half bridge with onboard gate drives, featuring the EPC1001 100V GaN Power Transistor. The purpose of this development board is to simplify the evaluation process of the EPC1001 GaN power transistor by including all the critical components on a single board that can be easily connected into any existing converter. The EPC9002 development board is 2” x 1.5” and contains not only two EPC1001 GaN transistors in a half bridge configuration with gate drivers, but also an on board gate drive supply and all critical components and layout for optimal switching performance. There are also various probe points to facilitate simple waveform measurement and efficiency calculation.

EL SEGUNDO, Calif.--(BUSINESS WIRE)—Efficient Power Conversion Corporation (EPC) today announced that the company has made available on its web site SPICE models for all of its enhancement mode GaN transistors.

TSPICE, PSPICE, and LTSPICE device models have been developed to help the designer of advanced GaN-based power conversion circuits and systems understand the value of this new power transistor family and reduce their time-to-market with benchmark products. These free downloads are available at:

A startup led by chip veteran Alex Lidow has officially announced its formation, disclosed its supply-chain partners and unveiled its first products in the emerging gallium nitride (GaN) arena.

EL SEGUNDO, Calif-March 8, 2010 -Efficient Power Conversion Corporation (EPC) today introduced a family of enhancement mode power transistors based on its proprietary Gallium Nitride on Silicon technology.

Spanning a range of 40 Volts to 200 Volts, and 4 milliohms to 100 milliohms, these power transistors demonstrate significant performance advantages over state-of-the-art silicon-based power MOSFETs. EPC’s technology produces devices that are smaller than similar resistance silicon devices and have many times superior switching performance. Applications that benefit from this newly available performance are DC-DC power supplies, point-of-load converters, class D audio amplifiers, notebook and netbook computers, LED drive circuits, telecom base stations, and cell phones, to name just a few.

EL SEGUNDO, Calif. - March 8, 2010 -Efficient Power Conversion Corporation (EPC) today announced that Digi Key Corporation will be the exclusive global distributor for EPC’s line of enhancement-mode Gallium Nitride power transistors.

The enhancement mode -normally OFF- GaN technology was explicitly developed to replace power MOSFETs. Says Alex Lidow, EPC’s co-founder and CEO, enhancement mode - rather than depletion mode - is essential for GaN to become a broad-scale silicon power MOSFET replacement.
