STMicroelectronics has GaN-based 250W industrial power supply demonstration board – the first for its MasterGaN power devices. Called EVLMG1-250WLLC, it is designed to produce 24Vdc 10A from a nominal 400Vdc supply with maximum efficiency above 92%. The main component is a MasterGaN1, an IC-like package containing a half-bridge driver and two normally-off 650V GaN transistors – ...
