PSR Flyback Reference Design for 120V+/-15% AC Input and 24V/6A Output


Design files


The PMP10912 reference design uses the UCC28630 primary-side regulated controller on a two-switch flyback controller  to generate a 24V/6A output from 120VAC input with safety isolation rated transformer. Over 87% efficiency is achieved at full load in this design.
