48V Input Synchronous Buck to 5V@10A Converter Reference Design

PMP11099

Design files

Overview

This synchronous buck converter operates over a 36V - 51V input range and delivers 5V @ 10A continuous. It achieves a peak efficiency of 92% at 8A and 48Vin. Other features include low output ripple voltage, excellent transient response and small size.

Features
  • Small size (33mm x 35 mm)
  • 92% efficient
  • 50mVpp output ripple voltage
  • Excellent transient response (<3% for 5A step)
