Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA – which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) for power management applications – has launched the EPC2051, a 100V GaN transistor with a maximum RDS(on) of 25mΩ and a 37A pulsed output current for high-efficiency power conversion in a small footprint.

The EPC2051 measures just 1.30mm x 0.85mm (1.1mm2) - 30 times smaller than a comparable silicon MOSFET - so applications demanding higher efficiency and power density no longer have to choose between size and performance, says the firm. Despite the small footprint of the chip-scale package, operating in a 50V–12V buck converter the EPC2051 achieves 97% efficiency at a 4A output while switching at 500kHz. In addition, the low cost of the EPC2051 brings the performance of GaN FETs at a price comparable to silicon MOSFETs.

Applications benefiting from this performance, small size and low cost include 48V input power converters for computing and telecom systems, LiDAR, LED lighting and Class-D audio.

“The ability of eGaN-based power devices to operate efficiently at high frequency widens the performance and cost gap with silicon,” says CEO Alex Lidow.

The EPC9091 development board is a 100V maximum-device-voltage half-bridge featuring the EPC2051, and the UP1966A gate driver from uPI Semiconductor. This 2” x 2” (50.8mm x 50.8mm) board is designed for optimal switching performance and contains all critical components for easy evaluation of the 100V EPC2051 eGaN FET.

The EPC2051 eGaN FET is priced at $0.67 each in 1000-unit quantities and $0.37 in 100,000-unit quantities. The EPC9091 development board is priced at $118.75 each. Both products are available for immediate delivery from distributor Digi-Key Corp.
