1.1 Introduction

This evaluation module includes a design with the TPS543B25T with thermally enhanced package with two M2x0.4 threaded steel spacers. The steel spacers are threaded and can be used to fasten a heat sink (heat sink not provided in kit). The output voltage is 1.0 V and switching frequency is 1 MHz.

This user’s guide contains information for the TPS543B25T evaluation module (BSR007) and the 25 A DC/DC converter. Also included are the schematic, and bill of materials for the TPS543B25TEVM.
