TPSM33625, TPSM3365F Evaluation Module
The TPSM33625EVM and TPSM33625FEVM enables the evaluation of the TPSM33625 and TPSM33625F
power modules. The EVMs allow for several configurations of the power module. Additionally, electrical test
points provide ease in verifying the performance of the power regulator. Lastly, these EVMs serve as a basis for
the TPSM33625 and TPSM33625F layout and component selection.

Page 3: Introduction
TPSM33625FRDNR, the fixed 1-MHz version of the TPSM33625 with mode selection and synchronization pin. The TPSM33625EVM is configured by default to be enabled with an output voltage of 5 V, and a switching frequency of 2.2 MHz with frequency foldback (auto mode) at light load. The TPSM33625FEVM is configured by default to be enabled with an output voltage of 5 V, and configured for auto mode. -
Page 4: Setup Procedure
Setup Procedure www.ti.com 2 Setup Procedure The following procedure outlines the steps to be taken for using the TPSM33625EVM and TPSM625FEVM. Use this section in conjunction with Section 3 to correctly setup the EVM. 1. Determine the output voltage that is to be evaluated, then reference Section 2. -
