Small and Simple Isolated Flyback Universal Vin, 5.2V@200mA, Primary-side Regulated Reference Design

Overview

TopologyFlyback Converter
Input voltage85-275 V
Output 15.2 V / 0.2 A
IC revisionA

Description

Design features low component count and low cost isolated flyback, converting the universal mains (85Vac…275Vac) to 5.2V@200mA. Due to primary side regulation of the controller UCC28700, no optocoupler is needed to close the loop.

Features

Remark: BOM is added with Schematic pdf.

  • Low component count
  • Low cost
  • Simple design
  • No optocoupler needed
