Development boards help to evaluate 200V GaN transistors
Designed to enable power systems engineers quickly evaluate the efficiency achieved with 200V GaN (gallium nitride) transistors in class-E amplifiers, current-mode class D, and push-pull converters operating up to 30MHz, Efficient Power Conversion (EPC) has released three GaN-based differential mode development boards.
The EPC9052, EPC9053 and EPC9054 can operate up to 30MHz. They are designed for class-E applications, such as wireless charging and can also 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 generic high voltage narrow pulse width applications such as LiDAR.
The boards feature 200V 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 have common preference specifications, while operating load conditions, including configuration, determine the optimal design load voltage and resistance.
A quick-start guide is available online, with set-up procedures, circuit diagram, performance curves, bill of material and Gerber files.
