TPS61170EVM-280
This user's guide describes the characteristics, operation, and use of the TPS61170EVM-280 evaluation
module (EVM). This EVM contains the Texas Instruments TPS61170 high-efficiency boost converter that
is configured to provide a regulated 24-V output voltage from an input voltage ranging from 9 V to 18 V.
The user's guide includes a schematic diagram, bill of materials and test data.

1 Introduction
This section contains background information for the TPS61170EVM-280 evaluation module.
1.1 Background
This TPS61170EVM-280 steps up 9-V to 18-V input voltages to a 24-V output. The goal of the EVM is to
facilitate evaluation of the TPS61170 power supply solution. The EVM uses the TPS61170 adjustable
output boost converter, external Schottky diode, input and output capacitors, inductor, and the appropriate
feedback and compensation components to provide 24 V.
