Overview

The PMP10145 reference design uses the UCC28610 flyback controller for the transition mode flyback topology. It generates an isolated output (9V@4.22A) from a wide AC input voltage range (80VAC - 291VAC). The controller maintains discontinuous mode operation and valley switching over the entire operating range. The UCC24630 synchronous rectifier controller provides good efficiency at heavy loads.

Features
  • Synchronous rectification
  • Wide input voltage range
