TPS65321EVM (HVL125A) User Guide
The Texas Instruments TPS65321EVM evaluation module (EVM) helps designers evaluate the operation
and performance of the TPS65321-Q1, a switch-mode DC-DC step-down converter with an integrated
low-dropout voltage regulator (LDO). This user guide describes how to setup and configure the EVM for
operation. The document includes the board layout, schematic, and bill of materials for the EVM.
