Hardware Jumper Override ? V_FIX
VFIX is an active low pin and when it is pulled low, the
controller enters V_FIX mode. The voltage regulator can be
powered when an external SVI bus master is not present.
When in VFIX mode, all of the voltage regulator ’s output
voltages will be governed by the information shown in
Table 4, regardless of the state of PWROK. VFIX mode is
for debug only. If VFIX mode is necessary for processor
bring ? up, VFIXEN, SVC, and SVD should be connected
with jumpers to either ground or VDDIO through suitable
pull ? up resistors. SVC and SVD are considered as static
VID and the output voltage will change according to their
status.

? The system power sequence logic asserts the
NCP5393B ENABLE pin:
? The NCP5393B will sample the VID1 line to
determine whether to start in SVI or PVI mode.
? The NCP5393B samples the voltage on the PSI_L
pin in order to determine the desired operating
configuration during power saving mode.
? The Boot VID is dependent on SVI or PVI mode
startup.
? The NCP593A V DD regulator (and VDDNB if in SVID
mode) will soft ? start and ramp to the initial Boot VID.
? VFIXEN mode is entered once VFIXEN is asserted and
the V DD and VDDNB regulators will regulate to the
VFIXEN VID.
? VFIXEN VID is captured from decoding the voltages
on the VID3/SVC and VID2/SVD pins per Table 4.
? If VFIXEN is asserted prior to the VID controller
reaching the Boot VID, the VID controller will move to

is as follows:
? 5 V is applied to the VCCA and VCCB pins to power
the NCP5393B and 12 V is applied to 12VMON.
? The NCP5393B samples the load on the G4 and G2
pins. If these pins are tied to ground the operating mode
will be altered from four phase mode, to three phase, or
