NCP5392P
is the summed current information from the VDRP minus
offset voltage. The overcurrent latch is set when the current
information exceeds the voltage at the ILIM pin. The
outputs are pulled low, and the soft-- start is pulled low. The
outputs will remain disabled until the V CC voltage is
removed and re-- applied, or the ENABLE input is brought
low and then high.
Output Overvoltage and Undervoltage Protection and
Power Good Monitor
An output voltage monitor is incorporated. During normal
operation, if the output voltage is 180 mV (typical) over the
DAC voltage, the VR_RDY goes low, the DRVON signal
remains high, the PWM outputs are set low. The outputs will
remain disabled until the V CC voltage is removed and
reapplied. During normal operation, if the output voltage falls
more than 350 mV below the DAC setting, the VR_RDY pin
will be set low until the output voltage rises.
Soft--Start
There are two possible soft-- start modes: AMD and
VR11. AMD mode simply ramps V core from 0 V directly
to the DAC setting at a fixed rate. The VR11 mode ramps
V core to 1.1 V boot voltage at a fixed rate of 0.8 mV/ m S,
pauses at 1.1 V for around 500 m S, reads the VID pins to
determine the DAC setting. Then ramps V core to the final
DAC setting at the Dynamic VID slew rate of up to
12.5 mV/ m S. Typical AMD and VR11 soft-- start sequences
are shown in the following graphs (Figure 9 and 10).
APPLICATION INFORMATION
The NCP5392P demo board for the NCP5392P is
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
Figure 6. Typical Load Step Response
(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
the lowest VID selection, then enable the test. See Figures
7 and 8.

software. Set the desired step load size, frequency, duty,
and slew rate. See Figure 6.
