1 Introduction

The output voltage of the TPSM33625EVM and TPSM33625FEVM can be configured from 1.8 V to 12 V with a load current up to 2.5 A. Measurement points are provided to easily measure conversion efficiency and look at other performance metrics. In addition, jumpers and test points are provided to evaluate the features of the TPSM33625 and TPSM33625F, such as programmable enable UVLO, adjustable switching frequency and mode select (or synchronization), and power-good flag.

The EVM layout allows the TPSM33625 and TPSM33625F and the orderable part numbers to be installed, and their specific features to be evaluated. The TPSM33625EVM comes installed with the TPSM33625RDNR, the adjustable switching frequency (RT pin) version of the TPSM33625. The TPSM33625FEVM comes installed with the 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. The following sections outline the step-by-step procedure to use the TPSM33625EVM and TPSM33625FEVM and the performance that is exhibited.
