Texas Instruments UCC28740 | Demoboard PMP4405

AC Input, Dual Output Power Supply Reference Design

Overview

TopologyFlyback Converter
Input voltage85-264 V
Output 15 V / 2 A
IC revisionE1

Description

The PMP4405 reference design uses the UCC28740 Flyback controller with valley-switching controller to generate dual DC output 5V/2A and 26V/0.3A from a universal AC input. The design is suited for auxiliary power for industrial applications and appliances. The design is fully tested and compliant with EMI regulations.

Features

  • Two isolated rails delivering 18W power
  • Valley switching for high efficiency
  • Output OVP,OCP and SCP protoction
  • Single layer board for low cost
  • SSR control with good cross-regulation
  • EMI compliance

Typical applications

  • Industrial applications and appliances
