PMP21814 Reference Design

Texas Instruments

4-Phase: 160-A synchronous buck converter reference design for communications processor power

Description

This reference design uses four TPS546D24A converters with integrated MOSFETs to support a full load of 160A at a 0.9V output. The system operates at a switching frequency of 650 kHz and has a PMBus interface that can be used to configure key converter parameters: including internal compensation. The detailed test report includes efficiency: thermal: stability: and load transient results.

Features
  • 12V input: 0.9V output with full load of 160AVery good output voltage regulation accuracy of 0.11% Accurate load sharing between 4 integrated convertersFixed-frequency current-mode control and programmable internal compensationPMBus interface for configuration and monitoring of key converter parametersDesigned for communications base-band and remote radio units
