Optocoupler-less Isolated Flyback Converter

Overview

TopologyFlyback Converter
Input voltage24 V
Output 1-15 V / 0.17 A
Output 215 V / 0.17 A

Description

We got the evaluation board test data and customer doesn't want us to disclose the project at the moment.This is a Vin=24V, Vout=±15V, Iout=0.165A design.This reference design is not online available to search, just for product promotion.

Features

  • Guaranteed long time supply availability for Industrial Applications.
  • No need for an optocoupler or a transformer tertiary winding.
  • The output voltage can be set by two external resistors and the transformer turns ratio.
  • Uses Original Adapted Type ON-Time Control Technology.
  • High-speed load response is realized and external phase compensation parts are unnecessary.
  • Fixed switching frequency and low output ripple
  • Highly efficient light load mode available (PFM operation)
  • Shutdown / Enable Control
  • Built-in N-Channel MOSFET
  • Soft start function
  • Output load compensation function
  • Protection functions:
    • VIN Under Voltage Lock-Out (VIN UVLO)
    • Over Current Protection (OCP)
    • Thermal Shutdown Protection (TSD)

Typical applications

  • Industrial equipment Isolated Power Supply
