ABSTRACT
This user's guide describes the setup and use of the TPS929240EVM evaluation module (EVM). This EVM
helps the user evaluate the features of the Texas Instruments TPS929240-Q1, which is an automotive 24-
channel LED driver with FlexWire interface, to address increasing needs of individual control of each LED
string. This document includes hardware setup instructions, software instructions, a schematic diagram, a bill of
materials and printed-circuit board layout drawings.
WARNING
Hot surface! Contact may cause burns. Do not touch!
Some components may reach high temperatures >55°C when the board is powered on. The user must
not touch the board at any point during operation or immediately after operating, as high temperatures
may be present.
