24Vin to 12Vout @ 100mA isolated push-pull reference design with cascode FETs

Overview

TopologyPush-Pull Converter symmetrical isolated
Input voltage24 V
Output 15 V / 0.25 A
IC revisionB

Description

This reference design extends the input voltage range on low-voltage push-pull controllers by employing cascode external FETs. The input voltage range is 12 V (+/-10%) or 24 V (+/-10%), with an output power of 1.2 W. The output voltage can be selected from two values, 12 V and 5 V, according to a list of four transformers.

Features

  • Low-cost solution, allowing high voltage isolation and low noise
  • No loop compensation (open loop)
  • Typical application: isolated gate driver power supply

Typical applications

  • AC analog input module, Multifunction relay, Processor module, Wired communication modules
