Texas Instruments TPS55165Q1-EVM, TPS55160Q1-EVM User Manual

User's Guide
SLVUAY1–November 2017
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 single­inductor 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 feedback­divider. The TPS55165-Q1 device has a selectable output voltage of 5 V or 12 V.

2.3 Layout and Component Placement
The TPS55160Q1-EVM and TPS55165Q1-EVM share the same PCB which is named HVL143B. The C1, C18, C19, and C22 capacitors are not installed. Their footprints allow for additional input
decoupling or bulk capacitance. The R6 and R7 resistors are not populated on the TPS55165Q1-EVM. Select the output voltage of either
5V or 12V using J6, which is named Vout_Set. The R6 and R7 resistors are populated on the TPS55160Q1-EVM. These resistors set the output voltage
to 8V. To eliminate the long trace to the J6jumper, which is prone to pick up noise, the R5 resistor and J6 jumper are not assembled on the TPS55160Q1-EVM.
Figure 4, Figure 7, and Figure 8 show the top layout of the EVM, with assembly options for the fixed
voltage version (TPS55165Q1-EVM) at the adjustable voltage version (TPS55160Q1-EVM).
