PMP8780, Primary-Side Regulated Flyback with 85 to 265 VAC Input with 12V@1A Reference Design
PMP8780, Primary-Side Regulated Flyback with 85 to 265 VAC Input with 12V@1A Reference Design. The PMP8780 reference design uses the UCC28700 primary-side regulated flyback controller to generate a 12V/1A output from a universal AC input. The valley switching of the UCC28700 allows this low-cost design to achieve an average efficiency over 83%, no load losses are less than 40mW
