TPS61170EVM-316
This user's guide describes the characteristics, operation, and use of the TPS61170EVM-316 evaluation
module (EVM). This EVM contains the Texas Instruments TPS61170 high-efficiency boost converter that
is configured in a SEPIC topology to provide a regulated 12-V output voltage from an input voltage ranging
from 9 V to 15 V. The user's guide includes a schematic diagram, bill of materials and test data.

This section contains background information for the TPS61170EVM-316 evaluation module.
This TPS61170EVM-316 converts 9-V to 15-V input voltages to a 12-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, output and flying capacitors, coupled inductor and
the appropriate feedback and compensation components to provide 12 V.
