This User’s Guide describes the characteristics, operation, and use of the TPS650240EVM-331 evaluation
module (EVM). This EVM is designed to help the user evaluate the TPS650240 and the TPS79901 in a
configuration for powering the iMX31 Processor. This User’s Guide includes setup instructions for the
hardware, a schematic diagram, a bill of materials (BOM), and PCB layout drawings for the evaluation
module.

The Texas Instruments TPS650240EVM-331 uses the TPS650240 Power Management IC and the
TPS79901 LDO in a configuration designed to meet the requirements for powering an iMX31 application.
The default settings of the EVM meet the voltage settings and the power sequencing requirements for the
iMX31 processor
In order for this EVM to operate properly, the following components must be connected and properly
configured.
The TPS650240EVM-331 PCB contains the TPS650240 IC and its required external components along
with the TPS79901. This board contains several jumpers and connectors that allow the user to customize
the board for specific operating conditions.
