Overview

The PMP10833RevA reference design is a compact and thermally efficient design intended to step down a wide range of AC inputs.  This design incorporates the UCC28C42, a current-mode PWM controller, with controllable frequencies up to 1Mhz.

Features
  • With an input of 230VAC, at a full load of 1A, efficiency is greater than 82%
  • Compact board size with a length of approximately 67mm
  • Good thermal performance
  • AC input range of 85VAC - 318VAC providing an output of 15V and 1A.
  • Test report available
