3W Isolated Triple Output Flyback Converter Reference Design

Overview

TopologyFlyback Converter
Input voltage10-14 V
Output 116 V / 0.06 A
IC revisionA

Description

PMP20852 is an isolated flyback converter reference design with primary-side regulation using the UCC2805 controller IC. There are three independently isolated outputs on the secondary side, each of which use LP2951 linear regulators to provide a well-regulated 16V output on each of the three rails. The design accepts an input voltage of 10Vin to 14Vin (12Vin Nominal) and provides three isolated 16Voutput rails capable of supplying 65mA each of continuous current to the load. The design is built on a 2-layer PCB with 1oz copper on each layer.

Features

  • Independently isolated triple output rails
  • Precision regulated outputs using LDOs
  • Primary-side regulated flyback achieves regulation without the need for an optocoupler

Typical applications

  • Micro inverter, String inverter
