TPS22924EVM-532
This user's guide describes the characteristics, operation, and use of the TPS22924EVM-532 evaluation
module (EVM). This EVM demonstrates the Texas Instruments TPS22924 load switch with controlled turn
on. The input voltage range of the TPS22924 is 0.75 V to 3.6 V. An integrated charge pump biases the
NMOS switch to achieve a minimum switch ON resistance. The switch is controlled by an on/off input
(EN), which is capable of interfacing directly with low-voltage control signals. This user's guide includes
setup instructions, schematic diagram, bill of materials, and printed-circuit board layout drawings for the
EVM.
