TPS26600-02EVM: Evaluation Module for TPS2660x
This user’s guide describes the evaluation module (EVM) for the Texas instruments TPS26600,
TPS26601, and TPS26602 devices. The document provides configuration information and test setup
details for working with the EVM. The EVM schematic, board layout and bill of materials (BOM) are also
included.
NOTE: The TPS26602 can be evaluated on this EVM by replacing the TPS26600PWP (U1) or
TPS26600RHF (U2) with the TPS26602PWP or TPS26602RHF, on respective channels.
Instructions for evaluation are listed in
Section 4.4.7 . The TPS26601 can be evaluated on
this EVM by replacing the TPS26600RHF (U2) with the TPS26601RHF. Instructions for
evaluation are listed in
Section 4.4.8 .
