FCC Warning
This equipment is intended for use in a laboratory test environment only. It generates, uses, and can
radiate radio frequency energy and has not been tested for compliance with the limits of computing
devices pursuant to subpart J of part 15 of FCC rules, which are designed to provide reasonable
protection against radio frequency interference. Operation of this equipment in other environments may
cause interference with radio communications, in which case the user, at their own expense, will be
required to take whatever measures may be required to correct this interference.

Introduction
The Texas Instruments TPS61193EVM evaluation module (EVM) helps designers to evaluate the
operation and performance of the TPS61193 or TPS61193-Q1 device. The TPS61193EVM uses the
TPS61193 or TPS61193-Q1 to drive up to 3 LED strings for LCD backlighting with high efficiency.
Information about output voltage and current ratings of the TPS61193 or TPS61193-Q1 can also be found
in the device data sheet.
A power supply connection for the V
IN
and test points for each signal can be found on the evaluation
board. A separate LED board can be used as a load; it is also possible to connect an LCD panel to the
output connectors.
For evaluation purposes, the EVM has been tested over a 4.5-V to 40-V input range. This voltage range is
within the recommended operating range for input voltage of the TPS61193 or TPS61193-Q1. Users are
cautioned to evaluate their specific operating conditions and choose components with the appropriate
voltage ratings before designing this circuitry into a final product.
