STMicroelectronics has added VIPerGaN65W, a 65 Watt flyback converter, in the VIPerGaN series that combines a 700V GaN transistor and quasi-resonant PWM control IC in a single QFN 5x6 package. Joining the VIPerGaN50W announced previously, the new VIPerGaN65W extends opportunities for customers to develop high-quality, cost-effective USB-PD chargers, fast battery chargers, and auxiliary power supplies that ensure superior user experiences. The flyback controller of these converters operates in quasi-resonant mode with zero-voltage switching (ZVS) up to the full load. Valley skipping optimizes efficiency at mid-to-high load, with ST’s proprietary valley locking to prevent noise at audio frequencies and thus ensure silent operation. With frequency foldback at light load, the conv
