Experience silent power with the advanced 700 V GaN converter
Combining high performance with silent operation for an enhanced user experience
ST introduces the new VIPerGaN flyback converter series featuring a proprietary technique that enables silent operation across all load levels. Designed for compact, high-efficiency USB-PD chargers, fast battery chargers, and auxiliary power supplies, these devices leverage GaN technology to deliver higher performance and an improved user experience while eliminating audible noise. The VIPerGaN50W, VIPerGaN65W, VIPerGaN100W, and VIPerGaN100WB converters integrate a 700 V GaN power transistor and a quasi-resonant PWM control IC in a single QFN 5 × 6 package, enabling efficient output power of up to 100 W.
