48V Input Synchronous Buck to 24V@12A (15A pk) Converter Reference Design

PMP11494

Design files

Overview

This synchronous buck converter operates over a 45V - 51V input range and delivers 24V @ 12A continuous (15A peak, 1 second). This converter is very efficient; achieving greater than 98% between 5.5A - 15A. The high efficiency helps reduce component temperature rise, improving operational life. Low output and input ripple voltage reduce conducted noise.

Features
  • Efficiency greater than 98%
  • High output power of 360W (24V @ 15A)
  • Low component temperature rise
  • Excellent transient response
