Overview
The TPS2560DRCEVM-424 is an evaluation module (EVM) designed by Texas Instruments to evaluate the performance of the TPS2560 power-distribution switch. This EVM is part of the TPS2506EVM-424 and TPS2561EVM-424 series, which are intended for engineering development, demonstration, or evaluation purposes. The module operates over a voltage range of 2.5 V to 6.5 V and is equipped with adjustable current-limit settings.
The TPS2560 switch itself is a current-limited, power-distribution switch with dual enable outputs and over-current status outputs. It features a single over-temperature shutdown and operates in current limit mode only. The EVM provides test points for convenient access to critical node voltages, making it an invaluable tool for engineers to test and evaluate the switch's performance under various conditions.
