Efficient Power Conversion (EPC) Introduces Monolithic Gallium Nitride Power Transistor Half Bridge Enabling over 97% System Efficiency for a 48 V to 12 V Point of Load Converter at 22 A Output

With the new 100 V EPC2104 eGaN®half bridge, a system efficiency of a complete buck converter using the EPC2104 is greater than 97% at 22 A switching at 300 kHz, and approaching 97% at 22 A when switching at 500 kHz, achieved when converting from 48 V to 12 V.

EL SEGUNDO, Calif. — April 2015 — EPC announces the EPC2104, 100 V enhancement-mode monolithic GaN transistor half bridge. By integrating two eGaN® power FETs into a single device, interconnect inductances and the interstitial space needed on the PCB are eliminated, resulting in a 50% reduction in board area occupied by the transistors. This increases both efficiency (especially at higher frequencies) and power density, while reducing assembly costs to the end user’s power conversion system.

The EPC2104 comes in a chip-scale package for improved switching speed and thermal performance, and is only 6.05 mm x 2.3 mm for increased power density. The EPC2104 is ideal for high frequency DC-DC conversion and motor drive applications.

Development Board

The EPC9040 is 2” x 2” and contains one EPC2104 integrated half-bridge component using the Texas Instruments LM5113 gate driver, supply and bypass capacitors. The board has been laid out for optimal switching performance and there are various probe points to facilitate simple waveform measurement and efficiency calculation.

Price and Availability

The EPC2104 monolithic half-bridge price for 1K units is $8,31 each

The EPC9040 development boards are priced at $137.75 each

Both are available for immediate delivery from Digi-Key at http://www.digikey.com/Suppliers/us/Efficient-Power-Conversion.page?lang=en

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 DC-DC converters, wireless power transfer, envelope tracking, RF transmission, power inverters, remote sensing technology (LiDAR), and Class-D audio amplifiers with device performance many times greater than the best silicon power MOSFETs.
