EPC adds 40V, 1.6mΩ eGaN FET for high-power-density telecom, netcom and computing solutions

Efficient Power Conversion Corp (EPC) of El Segundo, CA, USA – which makes enhancement-mode gallium nitride on silicon (eGaN) power field-effect transistors (FETs) and integrated circuits for power management applications – says that it is advancing the performance capability of low-voltage, off-the-shelf GaN transistors with the launch of the EPC2069 (1.6mΩ typical, 40V) eGaN FET.

The EPC2069 is suitable for applications with demanding requirements for high-power-density performance, including 48V–54V input servers. Lower gate charges and zero reverse recovery losses enable high-frequency operation of 1MHz, and beyond, at high efficiency in a 10.6mm2 footprint for state-of-the-art power density. The EPC2069 can support 48V–12V DC-DC solutions ranging from 500W to 2kW and exceed 98% efficiency. The use of eGaN devices in both the primary side and the secondary side are required to achieve maximum power density >4000W/in3.

“The EPC2069 is perfectly designed for the secondary side of the LLC DC-DC converter from 40V–60V to 12V, which is becoming very common for the new 48V–54V input servers required for high-density computing applications such as artificial intelligence and gaming,” says co-founder & CEO Alex Lidow. “This 40V device offers both smaller size and reduced parasitics compared with previous-generation 40V GaN FETs and at lower cost, thus offering designers both improved performance and cost savings.”

The EPC90139 development board is a 40V maximum device voltage, 40A maximum output current, half-bridge with onboard gate drives, featuring the EPC2069 eGaN FETs. The 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 EPC2069.

The EPC2069 eGaN FET is priced at 2.5K u/reel at $2.73 each. The EPC90139 development board is priced at $123.75/each. Both the EPC2069 and EPC90139 are available to order for immediate delivery from distributor Digi-Key Corp.
