Introduction
The Texas Instruments TPS4333xEVM evaluation module (EVM) helps designers evaluate the operation
and performance of the TPS4333x family of Switch Mode Power Supplies – Multiple-output voltage
regulator.
and performance of the TPS4333x family of Switch Mode Power Supplies – Multiple-output voltage
regulator.
The EVM contains one DC / DC converter (see

Input/Output Connector Description
J1 – Input is the protected power input terminal for the converter with a voltage range from 2V-40V (Boost
enabled) or 4V-40V (Boost disabled). The terminal block provides a power (V
enabled) or 4V-40V (Boost disabled). The terminal block provides a power (V
bat
) and ground (GND)
connection to allow the user to attach the EVM to a cable. harness. The power path provides a series
Schottky diode for reverse battery protection.

JP1 – DIV is the jumper used to select the output voltage for the boost pre-regulator stage. The boost
output is 7V when DIV is low, 10V when DIV floating and 11V when DIV is pulled high.
output is 7V when DIV is low, 10V when DIV floating and 11V when DIV is pulled high.
