TPS22901/02/02B Load Switch Evaluation Module (EVM)
This user guide describes the TPS22901/02/02B evaluation module (EVM). This guide contains the EVM
schematics, bill of materials, assembly drawings, and top and bottom board layouts.
The TPS22901/02/02B EVM is an evaluation module for the Texas Instruments family of low-input voltage,
ultra-low r
ON
load switches. This EVM operates over a 1 V to 3.6 V range and provides a continuous
output current of up to ≈ 110 mA. Additional open resistor and capacitor footprints allow for the use of
customer-selected input and output load values.
The TPS22901/02/02B EVM accepts a YFP-4 packaged load switch for any of three (3) possible devices:
TPS22901, TPS22902, or TPS22902B. These switches have a low threshold enable input, internally
controlled slew rate, and ultra-low quiescent/shutdown current. The TPS22902 and TPS22902B also
incorporate a 120- Ω quick output discharge resistor internally.
Table 2-1 summarizes the available EVM options.
