Texas Instruments TPS546D24A | Demoboard PMP21254

160-A, Four-Phase Reference Design Using the TPS546D24A Integrated FET Converter

Overview

TopologyBuck Converter
Input voltage6-13.2 V
Output 11.2 V / 160 A

Description

The PMP21254 is designed for powering high-current, low-voltage ASICs and FPGAs from a 5-V or 12-V rail. The design is optimized for high-density, and supports PMBus with current, voltage and temperature telemetry, if desired. A test report is included.

Features

  • Uses four TPS546D24A 40-A converters to create a 160-A supply with only four parts
  • Small double-sided design occupies one square inch each side per phase
  • Tested cut-and-paste design for powering high-current ASIC core rails
  • High speed on board dynamic load for testing to stringent dynamic load requirements
  • Fusion Digital Power Designer GUI enables easy prototyping through PMBus and manufacturing script generation

Typical applications

  • Data center switches, rack servers, Active antenna system, remote radio and baseband unit
