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.
