60W class-E amplifier development board evaluates GaN transistor for LiDAR
The development board enables power system designers to evaluate the high efficiency achieved with a high performance 200V GaN transistor in a class-E amplifier used in wireless power, LiDAR, current-mode class-D, and push-pull converters operating up to 15MHz.

The EPC9083 is a high efficiency, flexible, GaN-based differential mode development board that can operate up to 15MHz, including 6.78 MHz, popular for wireless power applications.  It is designed for class-E applications, such as wireless power, but can be used for any application where a low-side switch is used, for example push pull converters, current-mode class-D amplifiers, common source bi-directional switch, and high voltage narrow pulse width applications such as LiDAR.

It features the company’s EPC2046, 200V, 25mΩ eGaN FET. The EPC2046 allows even less switching loss than the previous generation of eGaN FETs, says the company, 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 are on the company website. The board is available for immediate delivery from distributor, Digi-Key.
