TPS22921/22/22B Load Switch Evaluation Module (EVM)

This user's guide describes the TPS22921/22/22B evaluation module (EVM). This guide contains the EVMschematics, bill of materials, assembly drawings, and top and bottom board layouts.

The TPS22921/22/22B EVM is an evaluation module for the Texas Instruments family of low-input voltage,ultra-low r

load switches. This EVM operates over a 0.9 V to 3.6 V range and provides a continuousoutput current of up to ≈110 mA. Additional open resistor and capacitor footprints allow for the use ofcustomer-selected input and output load values.

The TPS22921/22/22B EVM accepts a YFP-6 packaged load switch for any of three (3) possible devices:TPS22921, TPS22922, or TPS22922B. These switches have a low threshold enable input, internallycontrolled slew rate, and ultra-low quiescent/shutdown current. The TPS22922 and TPS22922B alsoincorporate a 120- Ωquick output discharge resistor internally.

Table 2-1 summarizes the available EVM options.
