PMP10816, Universal AC input, 48V/200W Primary-side Regulated Flyback Reference Design

PMP10816, Universal AC input, 48V/200W Primary-side Regulated Flyback Reference Design. The PMP10816 reference design uses the UCC28710 flyback controller to generate a 48V/200W output from a universal AC input. The primary-side regulation technique implemented by the UCC28710 eliminates the need for an Opto-coupler, reducing the size and cost of the design. In addition, the valley switching of the UCC28710 allows this design to achieve a maximum load efficiency over 89%, 87.5% average efficiency with 120VAC input and 88.6% average efficiency with 230VAC input
