Quarter Brick Dual Phase Synchronous Buck Converter for Enterprise Systems Server Reference Design

PMP20804

Design files

Overview

PMP20804 is a dual-phase synchronous buck converter reference design utilizing the LM5119 dual synchronous buck controller I.C. The design accepts an input voltage of 20V to 40V and provides a 12V output capable of supplying 33A of current to the load. This represents a power density design of 400W in a quarter brick footprint. The maximum component height is set by the Coilcraft VER2923-103 inductors at 0.875 in.

Features
  • Emulated peak current-mode control
  • High power density
  • External synchronization
  • 400W output power
  • Standard quarter brick footprint
