NCP5392Q
APPLICATION INFORMATION
The NCP5392Q demo board for the NCP5392Q is
the lowest VID selection, then enable the test. See Figures
7 and 8.
available by request. It is configured as a four phase
solution with decoupling designed to provide a 1 m Ω load
line under a 100 A step load.
Startup Procedure
Start by installing the test tool software. It is best to
power the test tool from a separate ATX power supply. The
test tool should be set to a valid VID code of 0.5 V or above
in order for the controller to start. Consult the VTT help
manual for more detailed instruction.
Step Load Testing
The VTT tool is used to generate the d i /d t step load.
Select the dynamic loading option in the VTT test tool
software. Set the desired step load size, frequency, duty,
and slew rate. See Figure 6.

(full load, 35 A -- 100 A)
Dynamic VID Testing
The VTT tool provides for VID stepping based on the
Intel Requirements. Select the Dynamic VID option.
Before enabling the test set the lowest VID to 0.5 V or
greater and set the highest VID to a value that is greater than
