PMP4242, 90VAC - 400VAC Input, 12V/3W Quasi-Resonant Flyback

PMP4242, 90VAC - 400VAC Input, 12V/3W Quasi-Resonant Flyback. The Reference design uses the UCC28600 quasi-resonant flyback controller to generate an isolated 12V/3W output from a extremely wide ranging 90VAC-400VAC input. The energy saving features of the UCC28600 allow this compact design to maintain high efficiency at heavier loads, while minimizing losses at light loads
