TPS65735 System Evaluation Board
This user’s guide describes the characteristics, operation, and use of the TPS65735EVM-703 evaluation
module (EVM). The TPS65735EVM-703 is a fully assembled and tested platform for evaluating the
performance of the TPS65735 single-chip power management device. This document includes schematic
diagrams, a printed circuit board (PCB) layout, bill of materials, and test data. Throughout this document,
the abbreviations EVM, TPS65735EVM, and the term evaluation module are synonymous with the
TPS65735EVM-703 unless otherwise noted.
