48V – 12V fully regulated isolated 1/4th brick module using digital control

Overview

TopologyFull-Bridge Converter symmetrical isolated
Input voltage36-75 V
Output 112 V / 50 A
IC revision1.0

Description

The REF_600W_FBFB_XDPP1100 is a system solution for telecom isolated DC-DC power modules that achieves 96% peak efficiency in DOSA standard quarter brick form factors. This reference design introduces a secondary side digital control and hard switching full-bridge topology delivering 12V/600W of output power. It operates across a wide range of input voltages (36V - 72V). The achieved power density is 22W/cm³ (360 W/in³), which is enabled by the use of the XDPP1100 digital controller, OptiMOS™ MOSFETs and an EiceDRIVER™ gate driver IC.

Features

  • Digital controlled isolated brick converter
  • Voltage mode control with flux balancing
  • Fast line and load transient response
  • PMBus™ and I2C communication
  • Voltage mode control with transformer flux walking protection
  • Best in class feed-forward response
  • Supports active current sharing between multiple modules
  • Smoother pre-bias start-up
  • Output voltage accuracy +/-1% over full temperature range -40°C to 125°C

Typical applications

  • Industrial 4.0
  • Isolated DC/DC brick module
  • Telecom infrastructure
  • Server motherboard / 48V Computing and datacenter SMPS
