1 Introduction

The output voltage of the TPSM365R15EVM and TPSM365R15FEVM can be configured for 1.8 V, 2.5 V, 3.3 V, 5 V, and 12 V with a load current up to 150 mA. 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 TPSM365R15 and TPSM365R15F, such as programmable enable UVLO, adjustable switching frequency and mode select (or synchronization), and power-good flag.

The EVM layout allows the TPSM365R15 and TPSM365R15F and their orderable part numbers to be installed, and their specific features to be evaluated. The TPSM365R15EVM comes installed with the TPSM365R15RDNR, the adjustable switching frequency (RT pin) version of the TPSM365R15. The TPSM365R15FEVM comes installed with the TPSM365R15FRDNR, the fixed 1-MHz version of the TPSM365R15 with mode selection and synchronization pin.

The TPSM365R15EVM 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 TPSM365R15FEVM is configured by default to be enabled with an output voltage of 5 V, and a switching frequency of 1 MHz with frequency foldback (auto mode) at light load. The following sections outline the step-by-step procedure to use the TPSM365R15EVM and TPSM365R15FEVM and the performance that is exhibited.
