TPS826xxEVM
This user’s guide describes the characteristics, operation, and use of the TPS826xxEVM-646 evaluation
module (EVM). The TPS826xxEVM-646 is a fully assembled and tested platform for evaluating the
performance of the TPS82671, TPS82672, TPS82675, TPS82690 and TPS82695 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 TPS826xxEVM and the term evaluation
module are synonymous with the TPS826xxEVM-646 unless otherwise noted.
