TPS2292xEVM-661

This user's guide describes the characteristics, operation, and use of the TPS2292xxEVM-661 evaluation

module (EVM). This EVM demonstrates the Texas Instruments TPS2292xx 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 (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.

1 Introduction

The TPS2292xxEVM-661 evaluation module (EVM) helps designers evaluate the operation and

performance of the TPS2292xx load switches. The board features the small 6-pin SOT25-6 package for a

small solution size.

Board Layout, Schematic, and Bill of Materials www.ti.com 5 Board Layout, Schematic, and Bill of Materials This section provides the TPS2292xxEVM-661 board layout, schematic, and bill of materials. 5.1 Board Layout For best performance, all traces should be as short as possible. To be most effective, the input and output capacitors should be placed close to the device to minimize the effects that parasitic trace inductances may have on normal and short-circuit operation.
