TPS22920EVM-002/TPS22920L
This user's guide describes the characteristics, operation, and use of the TPS22920EVM-002 and the
TPS22920L evaluation modules (EVM). This EVM demonstrates the Texas Instruments TPS22920 load
switch with controlled turn on. The input voltage range of the TPS22920 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.
1 Introduction
The TPS22920EVM-002 evaluation module (EVM) helps designers evaluate the operation and
performance of the TPS22920 load switch. The board features the small 6-pin CSP package for a small
solution size.

2 Setup
This section describes the jumpers and connectors on the EVM as well as how to properly connect, set
up, and use the TPS22920EVM-002.
2.1 J1/J3 – Input Connections
This is the connection for the leads from the input source. Connect the positive connection to the VIN J1
and the negative connection to the GND J3.
2.2 J4/J6 – Output Connections
This is the connection for the output of the TPS22920EVM. Connect the positive connection of the load to
the VOUT J4 and the negative connection to the GND J6.
