National Semiconductor Corp. (NYSE:NSM) today introduced the industry’s first 100V half-bridge gate driver optimized for use with enhancement-mode Gallium-Nitride (GaN) power field-effect transistors (FETs) in high-voltage power converters. Enhancement-mode GaN FETs enable new levels of efficiency and power density compared to standard metal-oxide semiconductor field-effect transistors (MOSFETs) due to their low on-resistance (Rdson) and gate charge (Qg) as well as their ultra-small footprint, but driving them reliably presents significant new challenges. National’s LM5113 driver integrated circuit (IC) eliminates these challenges, enabling power designers to realize the benefits of GaN FETs in a variety of popular power topologies.

EL SEGUNDO, Calif. - March 15, 2011 - Efficient Power Conversion Corporation (www.epc-co.com) announce the introduction of the EPC2001 and EPC2015, two lead-free, RoHS-compliant (Restriction of Hazardous Substances) enhancement-mode gallium nitride on silicon (eGaN™) FETs.

The EPC2001 FET is a 100 V_DS device with a maximum R_DS(ON) of 7 milliohms with 5 V applied to the gate, and the EPC2015 is a 40 V_DS with a maximum R_DS(ON) of 4 milliohms. Both eGaN FETs provide significant performance advantages over similar state-of-the-art silicon-based power MOSFETs. Both devices have low on resistance, are smaller than silicon devices with similar resistance and have many times superior switching performance.

Efficient Power Conversion Corporation (EPC) Market Leading eGaN™ FET Named Finalist in Prestigious 2010 EDN Innovation Awards Competition

EL SEGUNDO, Calif-February 23, 2011 - Efficient Power Conversion Corporation’s EPC1010 enhancement-mode gallium nitride on silicon (eGaN™) power FET has been named a finalist in EDN’s 21st annual Innovation Awards http://innovation.edn.com/) within the Power IC’s category.

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:
