4.1 Powering Up the EVM - GPIO Control

To power up the EVM follow the steps outlined below:

• Install WAKEUP jumper in the GND position.

• Install VCOM_CTRL jumper in the GND position.

• Install PWRUP jumper in the VIO position.

• Connect the EVM to the USB interface adapter using the 10-lead ribbon cable.

• Connect the USB interface connector to the computer USB port using a standard USB cable.

• Connect a 3-V - 6-V supply from the VIN terminal to GND.

• Move the WAKEUP jumper from the GND position to VIO position.

The TPS65185 should start immediately with the pre-defined power-up sequence and voltage settings.

NOTE: Please note that although in this example no software control and therefore no I

communication is required, the USB interface still needs to be connected. This is because

the interface board also provides the 3.3-V VIO rail. To operate the EVM without the

interface, connect a 3.3-V supply from VIO to GND.

5 Software Installation Instruction

The following section explains the procedure for installing the Graphical User Interface (GUI) onto a

Windows based PC. A USB interface adapter is required to connect the EVM to a PC and should have

been provided with the EVM.

Additional interfaces can be ordered through http://focus.ti.com/docs/toolsw/folders/print/usb-to-gpio.html.

If the software has been installed already, skip the following section and continue at Operating

Instructions.

To install the EVM software follow the steps outlined below:

• Copy the TPS65185 folder to your computer.

• Double-click on the setup.exe file in the TPS65185\Volume directory.

• Follow the prompts to finish the installation.

• At the end of the installation you may be asked to reboot your computer.
