TPS8267xEVM
This user’s guide describes the characteristics, operation, and use of the TPS8267xEVM-646 evaluation
module (EVM). The TPS8267xEVM-646 is a fully assembled and tested platform for evaluating the
performance of the TPS82671 and TPS82675 high-frequency, synchronous, step-down dc-dc converters
optimized for battery-powered portable applications. This document includes schematic diagrams, a
printed circuit board (PCB) layout, bill of materials, and test data. Throughout this document, the
abbreviations EVM and TPS8267xEVM and the term evaluation module are synonymous with the
TPS8267xEVM-646 unless otherwise noted.
