PMP8787, Primary-Side Regulated Flyback with 85-265VAC Input,(12V @ 0.5A)

PMP8787, Primary-Side Regulated Flyback with 85-265VAC Input,(12V @ 0.5A). PMP8787 reference design uses the UCC28700 flyback controller to generate a 12V/500mA output from a universal AC input. The primary-side regulation technique implemented by the UCC28700 eliminates the need for an optoCoupler, reducing the size and cost of the design. In addition, the valley switching of the UCC28700 allows this design to achieve a maximum load efficiency over 80%, no load losses are less than 40mW. The circuit board measures only 28mm by 33mm, with a maximum height below 20mm
