TPS6108xEVM-147
This user's guide describes the characteristics, operation, and use of the
TPS61081EVM-147 evaluation module (EVM). This EVM contains the Texas
Instruments high-efficiency boost converter that is configured to provide a regulated
12-V output voltage from a Li-ion battery, 3.3-V or 5-V input power supply. The user's
guide includes a schematic diagram, bill of materials (BOM), and test data.

This section contains background information for the TPS61080EVM-147 and TPS61081EVM-147
evaluation modules.
This TPS6108xEVM-147 uses either a TPS61080 or TPS61081 boost converter to step up 2.5-V to 6-V
input voltages to 12 V. The goal of the EVM is to facilitate evaluation of the TPS61081 power supply
solution. The EVM uses the TPS61080 or TPS61081 adjustable output boost converter and the
appropriate feedback components to provide 12 V.
Table 1 provides a summary of the TPS6108xEVM performance specifications. All specifications are given
for an ambient temperature of 25 ° C.
