TPS2291xxEVM-656
This user's guide describes the characteristics, operation, and use of the TPS2291xxEVM-656 evaluation
module (EVM). This EVM demonstrates the Texas Instruments TPS2291xx load switch with controlled
turn on. The device contains a P-channel MOSFET that can operate over an input voltage of 1.4V to 5.5V.
The switch is controlled by an on/off input (ON), 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.
1 Introduction
The TPS2291xxEVM-656 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS2291xx load switches. The board features the small 4-pin CSP package for a
small solution size.
