Figure 3. Device Selector

The device should be detected on the PMBus

and the initial load screen should appear as shown in

Figure 4.

Figure 4. Initial GUI Screen

If a device is not detected, an option is provided to rescan, ignore, or exit the GUI. If the hardware is

intended to be connected, check the USB connection to the PCB, FTDI connection to the evaluation

module, and verify that the power is present on the evaluation PCB by measuring the voltage between the

IN_S

and V

IN_GND

test points. Ignoring the detection message allows use of the integrated design tool

without the hardware connected.

Figure 5. LM5066 Block Level Representation

Click on the detected device ID (NSC-LM5066-AA) to display a block level representation of the device as

shown in Figure 5. The block level view of the device provides a display of all the telemetry data as well

as most of the faults and warnings supported by the device. The faults and warnings supported are

generally associated with an invalid input or output condition.

The faults shown on the left side of the block representation are generally associated with the input. These

include input under-voltage (UV), input over-voltage (OV), FET Fail (FF), and input over-power (OP). The

SMBus alert status, SMBA, is also shown on the left side and will turn red during any warning or fault

event. To facilitate the evaluation of the device, SMBus alerts are automatically cleared by the GUI.
