TPS5516xQ1-EVM Evaluation Module for 1-A Single-
Inductor Buck-Boost-Converter
The Texas Instruments TPS55160Q1-EVM and TPS55165Q1-EVM evaluation modules (EVMs) help
designers evaluate the operation and performance of the TPS55160-Q1 and TPS55165-Q1 1-A single-
inductor buck-boost converters. This user's guide describes how to set up and configure the EVMs for
operation. This document also provides the board layout, the schematic, and the bill of materials (BoM) for
the EVMs.
The TPS55160-Q1 device allows users to set the output voltage from 5.7 V to 9 V through a feedback-
divider. The TPS55165-Q1 device has a selectable output voltage of 5 V or 12 V.
