This user's guide describes the operation and use of the TPS6381xEVM evaluation module (EVM). The
EVM is designed to help users easily evaluate and test the operation and functionality of the TPS6381x
buck-boost converter family. The EVM has the output voltage set to 3.3 V or 3.45 V, depending on jumper
setting. The output voltage can be programmed via I
operates with an input voltage between 2.2 V and 5.5 V. The output current can go up to 2.5 A in buck
mode and up to 2 A in boost mode. This document includes setup instructions for the hardware, together
with the schematic and the PCB layout of the EVM. Throughout this document, the abbreviations EVM,
TPS6381xEVM, and the term evaluation module are synonymous with the TPS6381x, unless otherwise
noted.
