5.5 Software Operation

This section provides descriptions of the EVM software.

The supplied software is used to communicate with the TPS65279V EVM. Click on the icon on the host
computer to start the software. The software displays the main control panel for the user interface (

Figure 5-3

).

Check “Shutdown” box to shutdown

Buck 1 or Buck 2

Check “VID Enable” box to set to output

voltage by VID

Change Vout transition slew rate

Output Voltage Selection Pulldown Boxes

Mode Selection option

Internal Register Values, can be

altered bit by bit if desired. Updates register

when “Write” button is pushed.

Figure 5-3. Screen Capture of TPS65279V Software GUI Interface

Figure 5-3

 shows the GUI control interface. There are five 8-bit registers embedded in TPS65279V, two to select

the output voltage, two to configure the buck converter’s operation, and one for status feedback. Changes are
made by selecting and checking the components in the GUI on the left hand side and can also be made by
directly clicking the bits of each register. I

2

C address is set to default 0x60H, this address is corresponding

to the EVM jumper JP7 to connect to GND. Changing the I

2

C address requires that the EVM be configured

accordingly.

An option is to “write on change”, if this option is set to ON, any change is sent to the EVM immediately; if this
option is set to OFF, “Write” button or “W” button for each register must be clicked to send the control signal.

Register values can be read back from the EVM by clicking “Read” or “R” for each register.
