Texas Instruments UCC28710 | Demoboard PMP10168

Universal AC Input, Dual 12V, 5V Output PSR Quasi-Resonant Flyback Converter Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 112 V / 0.35 A
IC revisionA

Description

The PMP10168 reference design uses the UCC28710 primary-side regulated quasi-resonant fly back controller to generate a 12V and a 5V output from an universal AC input. It is a low cost solution because no opt-o coupler is needed to regulate the output voltages.

Features

  • 5V output referenced to primary side, 12V output referenced to 2ndary side (isolated)
  • 12W output power
  • Peak efficiency of 82%
  • No Need For an Op-to coupler
  • Fully built and tested design
  • Board dimensions: 72mm x 38mm
