40-W AC-DC isolated power supply reference design for industrial PLC application

Overview

TopologyFlyback Converter
Input voltage90-264 V
Output 124 V / 1.8 A
IC revision001

Description

This reference design provides 40W isolated 24-V and 5-V output with fly-back topology. The power supply can be powered from 90-264VAC Input. This design uses valley switching fly-back controller UCC28740 controller. The design achieves peak efficiency 86% and can support 3000uF capacitive load with startup time less than 500mS, it is a single side component placement PCB design which benefit manufacture cost.

Features
