Click on the install button; the PC gives a security warning and asks if the user wants to install this
application. Select Install to proceed. If a pre-release or Beta version is currently installed on the PC, the
user must uninstall this version of the software before installing the final version from either the CD or the
TI Web site.

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.

TPS6116x Controller EVM Software.
At start-up, the software first checks the firmware version of the USB-TO-GPIO adapter box. If an incorrect
firmware version is installed, the software automatically searches on the Internet (if connected) for
updates. If a new update is available, the software notifies the user of the update, and downloads and
installs the software. Note that after the firmware is updated, the user must disconnect and then reconnect
the USB cable between the adapter and PC, as instructed during the install process. The host PC
software also automatically searches on the Internet (if connected) for updates. If a new update is
available, the software notifies the user of the update and downloads and installs it.

The TPS61170 IC has a 5-bit register that stores the feedback voltage to which the error amplifier
regulates the FB pin. Using the EasyScale™ protocol, the user can program a separate digital IC to
generate a signal that changes this register to one of 32 discrete settings, thereby changing the FB
voltage and subsequent regulated output voltage. The software provides a GUI interface which allows the
user to change the bits directly or by a drop-down box. After changing the bits, the Write button must be
pressed. See a screen shot of the software in

In order to exit EasyScale™ mode, the IC needs to
be shutdown by pulling the CTRL low for 2.5ms and restarted.
