Where every mW counts
ST’s VIPerGaN family of high-voltage power converters is enhanced by the integration of GaN HEMT (high-electron-mobility transistor) technology. The use of GaN transistors results in higher power density, efficiency, and switching frequency, leading to smaller and lighter PCBs. This simplifies the design of SMPS (switched-mode power supplies) and improves their overall performance, meeting today’s demands for enhanced performance and energy-saving requirements. The new VIPerGaN65D further demonstrates these advancements, offering superior capabilities for medium power quasi-resonant ZVS flyback converters, for high power density and efficiency for compact, low-cost fast chargers, adapters, and various appliances.
