30h
Vboot
Vout max
If programmed by the platform, Refer to
Table 6
the VR supports V BOOT voltage
during start-up ramp. The VR
will ramp to V BOOT and hold at
V BOOT until it receives a new
SetVID command to move to a
different voltage.
This register is programmed by FBh
the master and sets the
maximum VID the VR will
support. If a higher VID code is
received, the VR will respond
with “not supported”
acknowledge.
31h
VID Setting
Data register containing
00h
currently programmed VID
voltage. VID data format.
32h
Power State
Register containing the
00h
programmed power state.
33h
Voltage Offset Sets offset in VID steps added to 00h
the VID setting for voltage
margining. Bit 7 is a sign bit,
0 = positive margin,
1 = negative margin.
Remaining 7 bits are # VID
steps for the margin.
00h = no margin,
01h = +1 VID step
02h = +2 VID steps...
34h
Multi VR
Config
Data register that configures
multiple VRs behavior on the
VR1: 00h
VR2: 01h
same SVID bus.

LAYOUT GUIDELINES
Connect this ground pad to the ground plane through low impedance path. Recommend use of at least 5 vias to connect
to ground planes in PCB internal layers.
Follow Intel recommendations.
No special consideration.
The NTC thermistor needs to be placed close to the thermal source that is monitored to determine the desired VR_HOT#
and thermal ALERT# toggling. Recommend placing it at the hottest spot of the ISL6353 based regulator.
Place the resistor and capacitor from VW to COMP in close proximity of the controller.
