2.2 Software Setup
Setup
This jumper is used to tie the I
2
C™ SCL pin of the TPS62351 to either a 10-k Ω pull-up resistor to the input
voltage or to short SCL to ground. The shunt can be removed if the I
2
C™ master has its own pull up or
operates from a voltage that is different than the input voltage of the TPS62351. The Texas Instruments
USB Interface Adapter provides an active pull up so no jumper should be installed when using the adapter
supplied with the EVM.

This jumper enables or disables the converter. Connect the shorting jumper from the center ENABLE pin
to either the ON or OFF position. This pin should never be left floating.
This jumper is used to select the output voltage of the converter. Placing a shunt between pins 1 and 2
(HIGH and VSEL) sets the output voltage of the converter to the voltage defined by the internal VSEL1
register. Placing a shunt between pins 2 and 3 (VSEL and LOW) sets the output voltage of the converter
to the voltage defined by the internal VSEL0 register.

If installing from a CD, insert the CD and run Setup.exe, follow all the prompts to allow the software to be
installed.
If installing from the web, go to the following URL www.ti.com .
Note: this installation page is best viewed with Microsoft Internet Explorer browser (It may not work
correctly with other browsers).
Click on the install button, the pc should give a security warning to the user, and ask if the user wants to
install this application, select Install to proceed.
With both types of installation, the software attempts to install the Microsoft Dot Net Framework 2.0 (if it is
not already installed) This framework is required for the software to run.
After installation the software should automatically run.
During future use of the software, it may prompt the user to install a new version if it becomes available on
the web.
