The EPC9083 differential mode development board enables power system designers to evaluate the high efficiency achieved with a high performance 200V gallium nitride transistor in a class-E amplifier for wireless power, LiDAR, current-mode class-D, and push-pull converters operating up to 15 MHz – including 6.78 MHz as used in wireless power applications. Other application examples include push-pull converters, current-mode class-D amplifiers, common source bi-directional switches, and high voltage narrow pulse width applications such as LiDAR.

The EPC9083 features the EPC2046 200V, 25 mΩ eGaN FET. The EPC2046 allows less switching loss than the previous generation of eGaN FETs, in a 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 are provided on the evaluation kits page. The EPC9083 is priced at $158.13 each and is available at Digi-Key.
