EPC’s new development boards enable power systems designers to easily and quickly evaluate the high efficiency achieved with 200 V gallium nitride transistors in class-E amplifiers, current-mode class-D, and push-pull converters operating up to 30 MHz.
EL SEGUNDO, Calif.— January 2016 — Providing 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, Efficient Power Conversion Corporation (EPC) announces high efficiency, GaN-based differential mode development boards that can operate up to 30 MHz.
These development boards are designed for class-E applications, such as wireless charging, 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 generic high voltage narrow pulse width applications such as LiDAR.
These development boards feature 200 V rated eGaN® FETs. 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.
All three boards have common preference specifications. The operating load conditions, including configuration, determine the optimal design load voltage and resistance. The device parameters for each board are given in the following table:
