STMicroelectronics VIPERGAN50, 65 and 100
Advanced quasi-resonant offline high voltage converter with E-mode GaN HEMT
ST’s VIPer® family of high-voltage power converters is enriched with the introduction of GaN HEMT (high-electron-mobility transistor) technology.
The use of a GaN transistor in the VIPerGaN® series (VIPERGAN50, VIPERGAN65 and VIPERGAN100) leads to higher power density, efficiency, and switching frequency with a consequently smaller and lighter PCB, simplifying the design of SMPS and improving their overall performance.
