TPS6261x/TPS6262x/TPS6266xEVM
This user’s guide describes the characteristics, operation, and use of the TPS6261x/2x/6xEVM-419
evaluation module (EVM). The TPS626xxEVM-419 is a fully assembled and tested platform for evaluating
the performance of the
evaluation module (EVM). The TPS626xxEVM-419 is a fully assembled and tested platform for evaluating
the performance of the
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, TPS626xxEVM, TPS6261x/2x/6xEVM, and the term evaluation module are
synonymous with the TPS6261x/2x/6xEVM-419 unless otherwise noted.
