Functional Pin Description
VCC
VCC is the bias supply for the ICs small-signal circuitry. Connect
this pin to a +5V supply and locally decouple using a quality
1.0μF ceramic capacitor.
PVCC
This pin is the power supply pin for the MOSFET drivers. This
pin can be connected to any voltage from +5V to +12V,
depending on the desired MOSFET gate drive level.
GND
GND is the bias and reference ground for the IC.
ENLL
This pin is a threshold-sensitive (approximately 0.66V) enable
input for the controller. Held low, this pin disables controller
operation. Pulled high, the pin enables the controller for
operation. ENLL has a internal 1.0μA pull-up to 5V.
FS
A resistor, placed from FS to ground, will set the switching
frequency. Refer to Equation 34 for proper resistor calculation.

VID4, VID3, VID2, VID1, VID0, and VID12.5
These are the inputs for the internal DAC that provides the
reference voltage for output regulation. These pins respond to
TTL logic thresholds. The ISL6568 decodes the VID inputs to
establish the output voltage; see VID Tables for
correspondence between DAC codes and output voltage
settings. These pins are internally pulled high, to
approximately 1.2V, by 40μA (typically) internal current
sources; the internal pull-up current decreases to 0 as the VID
voltage approaches the internal pull-up voltage. All VID pins
are compatible with external pull-up voltages not exceeding
the IC’s bias voltage (VCC).
The VID12.5 pin also serves as the internal DAC compliance
selector. The way this pin is connected selects which of the
three internal DAC codes will be used. For VRM10 codes this
pin must be less that 3V. To encode the DAC with Intel VRM9.0
codes, connect the VID12.5 pin to a +5V source through a
50k Ω resistor. To encode the DAC with AMD Hammer VID
codes, connect this pin to a +5V source through a 5k Ω resistor.
