Description

The PMP10871 reference design uses the UCC2897A to control an active clamp forward and converts an 18-36V input to an isolated 5V/4A output with efficiency over 92%.  This compact design uses only surface mount components.

Features
  • High efficiency (greater than 92%)
  • Self-Driven Synchronous Rectifiers
  • 100% Surface Mount Components
  • All Ceramic Output Capacitors
