TPS62125EVM-044 Evaluation Module
This user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62125
evaluation module (EVM). This EVM is designed to help the user easily evaluate and test the operation
and functionality of the TPS62125. The EVM converts a 4-V to 17-V input voltage to a regulated 3.3-V
output voltage that delivers 300 mA. This user’s guide includes setup instructions for the hardware,
printed-circuit board layouts for the EVM, a schematic diagram, a bill of materials, and test results for the
EVM.
