Description

The PMP8832 reference design uses the UCC28700 primary-side regulated flyback controller to generate a 12V/1.1A output from a universal AC input. The valley switching of the UCC28700 allows this low-cost design to achieve an average efficiency greater than 83%; no load losses are less than 40mW.

Features
  • Low cost - Primary Side Regulation eliminates opto and TL431
  • Passes class B conducted emissions without a common-mode inductor
  • No load power consumption is below 40mW
