Description

The PMP8781 reference design uses the UCC28700 primary-side regulated flyback controller to generate a 16.5V/1A output from a univeral AC input. The valley switching of the UCC28700 allows this low-cost design to achieve a maximum load efficiency near 85%; no load losses are less than 50mW.
