24V Input Voltage Two Phase Synchronous Buck Converter (12V@20A) Reference Design

PMP20021

Design files

Overview

This two phase synchronous buck converter allows smaller components with better distributed thermal performance than an equivalent single phase design. It achieves high efficiency, uses small inductors and easily fits in a small PCB area of 70mm x 70mm.

Features
  • High efficiency (95% with 20A load at 24Vin)
  • Small inductors
  • Excellent current sharing between phases
