High-Current 360-A Static / 600-A Peak Core PMBus Voltage 12-phase Reference Design for ASICs

Overview

TopologyBuck Converter
Input voltage10-14 V
Output 11.2 V / 360 A
IC revisionA

Description

The PMP21887 is a 12-phase Power Management Bus (PMBus) buck converter powering Datacenter Hardware Accelerator, Enterprise Switch and Router application-specific integrated circuit (ASIC) core rails. It provides 360A of continuous current and 600A of peak current at 0.85-V nominal voltages. It uses twelve of TI's CSD95480 common footprint 70-A smart power stages. Design includes an on-board high speed dynamic load for testing to stringent dynamic load response requirements of high speed ASICs. The PMP21887 includes a Test Report showing these capabilities and enables a cut-and-paste design for powering high-current ASIC core rails with PMBus.

Features

  • Uses twelve CSD95480 common footprint 70-A smart power stages
  • Fusion Digital Power Designer GUI enables easy prototyping through PMBus and manufacturing script generation
  • DCAP+ control mode enables the fastest load transient response and output capacitor (including ceramic cap) reduction
  • High speed on board dynamic load for testing to stringent dynamic load requirements
  • Tested, cut-and-paste design for powering high-current ASIC core rails

Typical applications

  • Data center switch
