TPS62130EVM-505, TPS62140EVM-505, and
TPS62150EVM-505 Evaluation Modules
This user’s guide describes the characteristics, operation, and use of the Texas Instruments TPS62130,
TPS62140, and TPS62150 evaluation modules (EVM). These EVMs are designed to help the user easily
evaluate and test the operation and functionality of the TPS62130, TPS62140, and TPS62150. This user’s
guide includes setup instructions for the hardware, printed-circuit board layouts for the EVMs, a schematic
diagram, a bill of materials, and test results for the EVMs. After the release of the A-version devices in the
summer of 2013, these EVMs are assembled with the TPS62130A, TPS62140A, or TPS62150A.
