TPS65132L Evaluation Module

This user's guide describes the characteristics, operation, and use of the TPS65132L evaluation module
(EVM) and its software. It includes the EVM specifications, the recommended setup (hardware and
software), the schematic diagram, the board layouts, and the bill of materials.

All the measurements in the

Application Performance

section of the TPS65132L datasheet (

SLVSBM1

)

were done with this EVM.
