Figure 46. Change View Screen to Monitor Screen

When the Monitor screen is selected (Figure 47), the screen changes to display real-time data of the

parameters that are measured by the controller. This screen provides access to:

• Graphs of Vout, Iout, Temperature, and Pout. As shown, Pout display is turned off.

• Start/Stop Polling which turns on or off the real-time display of data.

• Quick access to On/Off config

• Control pin activation, and OPERATION command. As shown, because the device is configured for

Always Converting, these radio buttons are either grayed-out or have no effect.

• Margin control.

• PMBus log which displays activity on the PMBus.

• Tips & Hints which displays additional information when the cursor is hovered over configurable

parameters.

As shown, when the EVM is still off due to UVLO, no output voltage or current is displayed.

At first GUI launch, Faults may occur due to communications during power up. These faults can be

cleared once the device is enabled.
