Efficient Power Conversion introduces the EPC2102, 60 V and EPC2103, 80 V half bridges, expanding its award winning family of gallium nitride power transistor products.
EL SEGUNDO, Calif. — January 2014 — EPC announces the EPC2102, 60 V and the EPC2103, 80 V enhancement-mode monolithic GaN transistor half bridges. 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 half bridges are ideal for high frequency DC-DC conversion.
Using an EPC2103 in a typical buck converter, system efficiency is greater than 97% at 20 A, when switching at 500 kHz and converting from 48 V to 12 V. A second device, the EPC2102 60 V half bridge is also being added to the portfolio. This device achieves 98% system efficiency at 18 A, when switching at 500 kHz and converting from 42 V to 14 V.
Both products come in a chip-scale package for improved switching speed and thermal performance and are only 6.05 mm x 2.3 mm for increased power density.
