TPS61175EVM-588
This user’s guide describes the characteristics, operation, and use of the TPS61175EVM-588 evaluation
module (EVM). This EVM contains the Texas Instruments TPS61175 high-efficiency boost converter that
is configured in a split-rail, single-ended primary inductance converter (SEPIC) to provide a regulated 12-V
output voltage from an input voltage ranging from 9-V to 24-V. This user’s guide includes a schematic
diagram, board layout, bill of materials, and test data.
