PMP20071 Reference Design

Texas Instruments

Reference Design: 8.5V-13.2V to 1.2V 50A DC/DC Converter

Description

The TPS546C20A provides a single IC for both control & the synchronous power stage for high current DC/DC applications and allows doubling of the current capability with use of two of the same part.  Multi-phase also allows output ripple cancellation and effective higher bandwidth control for a given switching frequency. PMP20071 shows a high current two phase application. The Test Report show the loss sharing between the two power stages: output ripple reduction and improved dynamic response due to the two phases.

Features
  • Complete high current 2 phase DC/DC converter with all the advantages of phase interleaving using only two of the single phase partsFixed frequency voltage mode control allows for user selection of switching frequency and synchronization to an external clockOutput voltage: current limit and fault thresholds / responses can be adjusted on the fly" thru the PMBus interfaceRich test interface including PMBus socket: and high speed dynamic test loadSchematic: BOM: layout and Test Report focusing on thermal performance & load dynamics"
