The PMP8869 reference design uses the UCC28700 primary-side regulated flyback controller to generate a 12V/250mA output from a universal AC input. The valley switching of the UCC28700 allows this low-cost design to achieve a maximum load efficiency over 80%; no load losses are less than 30mW. This circuit fits onto a 23mm x 37mm PCB.
Remark: BOM is added with Schematic pdf.
