EPC Introduces GaN Based Amplifier Development Board for Wireless Power Applications

Efficient Power Conversion Corporation (EPC) has unveiled the EPC9083, a high efficiency, flexible, 60 W GaN-based differential mode development board that provides an easy-to-use way for power systems designers to evaluate the exceptional performance of gallium nitride transistors and get their products into volume production quickly. The EPC9083 can operate up to 15 MHz, including 6.78 MHz which is popular for wireless power applications.

This development board is designed for class-E applications, such as wireless power, but can be used for any application where a low-side switch is utilized. Examples include, but are not limited to, push-pull converters, current-mode class-D amplifiers, common source bi-directional switch, and high voltage narrow pulse width applications such as LiDAR.

The EPC9083 features the EPC2046, EPC’s latest generation 200 V, 25 mO eGaN FET. The EPC2046 allows even less switching loss than the previous generation of eGaN FETs, in an even smaller size, while keeping the same drain-source on-resistance. The amplifiers are set to operate in differential mode and can be re-configured to operate in single-ended mode and include the gate driver and logic supply regulator.

A Quick Start Guide, containing set-up procedures, schematic, and bill of material for the boards, is provided on-line. The EPC9083 is priced at $158.13 each and is available for immediate delivery from Digi-Key. Click here to order.
