Efficient Power Conversion (EPC) Launches 170 V eGaN® FET Offering Best-in-Class Synchronous Rectification Performance and Cost to Seize High End Server and Consumer Power Supply Applications

Sponsored by Businesswire

Efficient Power Conversion Corporation, the world’s leader in enhancement-mode gallium nitride on silicon (eGaN) power FETs and ICs, advances the performance capability while lowering the cost of off-the-shelf gallium nitride transistors with the introduction of the EPC2059 (6.8 mΩ, 170 V) eGaN FET. This device is the latest in a family of 100 V – 200 V solutions suitable for a wide-range of power levels and price points. They are designed to meet the increasing demands of 48 V – 56 V server and data center products as well as an array of consumer power supply applications for high end computing, including gaming PCs, LCD/LED TVs, and LED lighting.

The EPC2059 is ideal for DC-DC secondary-side synchronous rectification in AC/DC adaptors, fast chargers, and power supplies with power ranges between 100 W and 6 kW. The performance advantage of gallium nitride devices helps designers achieve the demanding efficiency requirements for 80 Plus Titanium power supplies, while providing smaller, faster, cooler, and lighter systems with lower system costs than currently available solutions.

According to Alex Lidow, EPC’s co-founder and CEO, “There are very significant performance advantages gained from using GaN in the secondary-side synchronous rectification socket of AC/DC adaptors. In a 400 V to 48 V conversion, switching at 1 MHz, GaN has shown to have one-sixth the losses and run 10 degrees cooler than a silicon MOSFET with equivalent on resistance. This enables designers to meet the latest stringent energy efficiency standards for high-end computing, where growth is exploding for multiple applications, such as artificial intelligence (AI), cloud computing, and high-end gaming systems.”

Development Board

The EPC9098 development board is a 170 V maximum device voltage, 25 A maximum output current, half bridge with onboard gate drives, featuring the EPC2059 eGaN FETs. This 2” x 2” (50.8 mm x 50.8 mm) board is designed for optimal switching performance and contains all critical components for easy evaluation of the EPC2059.

Price and Availability

The EPC2059 is priced at $1.59 each in 2.5Ku volumes.

The EPC9098 development board is price at $123.75 each.

The EPC2059 and EPC9098 are available to order from Digi-Key at

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. EPC also has a growing portfolio of eGaN-based integrated circuits that provide even greater space, energy, and cost efficiency.
