PMP5394, 90VAC-400VAC Input 24V/3W Quasi-Resonant Flyback Reference Design

PMP5394, reference design provides and isolated 24V at 125mA from a wide range AC input. The UCC28600 flyback controller used in this design reduces standby power consumption by operating in burst mode at light loads, and increases efficiency at heavier loads by reducing switching losses through quasi-resonant valley switching
