24V Input Synchronous Buck to 12V at 8A Converter Reference Design

PMP10799

Design files

Overview

This synchronous buck converter operates over a 19-V to 32-V input range and delivers 12 V at 8-A continuous. It achieves an efficiency of greater than 97% between 4.5 A to 8 A at 24 Vin. Other features include low-output ripple voltage, excellent transient response, and small size.

Features
  • Small size (33 mm x 35 mm)
  • Greater than 97% efficient
  • 50-mVpp output ripple voltage
  • Excellent transient response (<2% for 8-A step)
