Flyback Reference Design with High Line AC Input and 5V, 12V Dual-Output

Overview

TopologyFlyback Converter
Input voltage185-260 V
Output 112 V / 0.9 A
IC revisionA

Description

The PMP11405 reference design uses the UCC28740 constant current (CC), constant voltage (CV) flyback controller for a 5V/1A, 12V/0.9A bias supply with high line AC input (185VAC to 260VAC input). With safety isolated, Over 80% efficiency is achieved at full load and less than 400mW power consumption is observed during no load condition
