High Frequency (750kHz) 48V to 24V/0.7A Flyback Converter Reference Design
Description
The PMP21002 reference design is a high frequency flyback converter with a 42-57Vdc input and an isolated 24V/0.7A output. The LM5020 is a current mode PWM controller with an integrated start-up regulator. The 750kHz switching frequency allows operation above noise sensitive frequencies and results in small size. This reference design is well suited for PoE or telecom applications.
