I received the Infineon CoolGaN Class D amplifier EVAL_AUDAMP24 evaluation module GaN today. Will be powering with generic PSU +/- 50V. Many built in protection features built in the evaluation board.
From the brochure:
"The EVAL_AUDAMP24 GaN e-mode High Electron Mobility Transistor (HEMT) evaluation board is a two-channel, 225 W/ch (4 Ω at ±43 V) or 250 W/ch (8 Ω at ±63 V) half-bridge class D audio power amplifier for Hi-Fi audio systems. This evaluation board demonstrates how to use the CoolGaN™ gallium nitride transistor, IRS20957S controller IC, implement protection circuits, and design an optimum PCB layout using the IGT40R070D1 E8220, CoolGaN™ gallium nitride transistor. The reference design provides all the required housekeeping power supplies for ease of use. The two-channel design is scalable for power and the number of channels. "
