Universal Input to 15V@400mA PSR Non-Isolated Flyback with Integrated 700V Switch Reference Design

Overview

TopologyFlyback Converter
Input voltage90-265 V
Output 115 V / 0.4 A
IC revisionB

Description

A quasi-resonant non-isolated Flyback supplies 15V @ 400mA from universal input voltage (90Vac to 265Vac). A LC filter has been added on input terminals to comply with CENELEC EN50065-1 regulations and make this power supply suitable for Power Line Communication. The efficiency curve value remains almost flat (72% to 85%) in the power range of 10%...100% and in the whole input voltage range.

Features

Simple non-isolated PSR flyback converter with integrated 700V FETCompact solution (28.4mm x 67.4mm) supplies 6W with almost flat efficiency from 50mA to 400mA load (72%...85%)Good output voltage regulation versus load: +/-5% in the whole temperature rangeVery low noise solution, suitable for PLC applications, complying with CENELEC EN50065-1

Typical applications

  • Data Concentrators
  • Power Line Communications
  • Electricity Meter
