9.1 Main Window

Once the device is selected the main window should look like the screenshot in Figure 7.

Figure 7. Main Window

The main window consists of six different items:

• Select VID Operating Mode: This section allows the user to switch between 4-Bit and 6-Bit

communication mode. The mode jumper must be manually positioned on the actual evaluation board if

the mode is toggled.

• Initial Setup: The Initial Setup section allows the user to enter the design inputs based on the

application requirements of the VID enabled POL. The default values in this section represent the

values used in on the evaluation module.

• Resistor and Vout Values (Calculated): R

FB1

and R

FB2

components along with output voltage

parameters in the Resistor and Vout Values section are the resulting values calculated using the user

inputs in the Initial Setup section.

• Output Voltage: Use the Output Voltage section to change the nominal output voltage directly.

• Margin Control: The user can set the exact margining value in the Margin Control section. The user

can then use the "Margin Up' and "Margin Down" buttons to adjust the output voltage up or down

depending on the value in the Margin Desired box. The percent of margining is based on the value in

the Nom Vout (Actual) box in the Output Voltage section.

• Block Level Schematic:The LM10011 GUI shows a block level schematic. This schematic displays

the present value of the POL output and allows the user to control the VID codes directly.
