Efficient Power Conversion Corporation (EPC) has announced high efficiency, GaN-based differential mode development boards that can operate up to 30 MHz. These boards provide 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.
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.
