The PMP8930 reference design uses the UCC28710 primary-side regulated flyback controller to generate a 20V output from a univeral AC input. a bulk capacitor with slow-charge-fast-discharge circuit is placed at flyback output to provide long hold up time for the following step-down DC-DC stages. TPS54335 is used as the controller and power stage for the main 4V or 12V output. The valley switching of the UCC28710 allows this low-cost design to achieve a maximum load efficiency of 83%; no load losses are less than 70mW.
