STACF01A/STACF01B Flyback Controller ICs

STMicroelectronics STACF01A/STACF01B Active Clamp Flyback Controller ICs drive and control active clamp flyback converters with non-complementary driving of the active clamp (high-side, HS) switch. It is intended explicitly for high-performance AC-DC adapters with GaN HEMTS rated up to 100W and beyond, aimed at high efficiency and power density. The ICs seamlessly change operating mode with loading conditions to optimize efficiency under an extremely wide range of loads: variable frequency with frequency foldback at heavy-medium load, bottom-clamped, load-proportional frequency at light load, burst mode at very light, and no-load.
