Offline AC/DC 75W 2-Switch Quasi-Resonant Flyback Converter Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 119.5 V / 3.84 A
IC revisionC

Description

This design uses the LM5023 flyback controller for the 2-Switch Quasi-Resonant Flyback Topology. It generates an isolated output (19.5V@3.84A) from an universal input (85VAC - 265VAC).
