24V to 12V@4.5A Synchronous Buck Converter Reference Design

PMP10902

Design files

Overview

This synchronous buck converter supplies 12V @ 4.5A from a 12.5V to 24V input. This converter was optimized to provide high efficiency in a small footprint for applications such as portable radios.

Features
  • Small area of less than 25mm x 40mm
  • Excellent efficiency (96.5% at 24Vin, 97.2% at 18Vin)
  • Low profile (4mm height)
