TLV62130EVM-505 and TLV62150EVM-505 Evaluation
Modules
This user’s guide describes the characteristics, operation, and use of the Texas Instruments TLV62130
and TLV62150 evaluation modules (EVM). The TLV62130EVM-505 and TLV62150EVM-505 evaluate the
performance of the TLV62130 or TLV62150 IC in a standard buck regulator topology. The EVM converts
a 4-V to 17-V input voltage to 3.3 V and provides up to 3 A (1 A for the TLV62150EVM-505) of output
current. The user’s guide includes setup instructions for the EVM, the printed-circuit board layout, the
schematic diagram, the bill of materials, and test results for the EVM. After the release of the A-version
devices in the summer of 2013, these EVMs are assembled with the TLV62130A or TLV62150A.
