Functional Pin Description
VCC (Pin 3)
Bias supply for the IC’s small-signal circuitry. Connect this pin
to a +5V supply and locally decouple using a quality 1.0μF
ceramic capacitor.
PVCC (Pin 15)
Power supply pin for the MOSFET drive. This pin can be
connected to any voltage from +5V to +12V, depending on
the desired MOSFET gate drive level.
GND (Pin 33)
Bias and reference ground for the IC.
ENLL (Pin 20)
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.

FS (Pin 29)
A resistor, placed from FS to ground, will set the switching
frequency. Refer to Equation 43 and Figure 24 for proper
resistor calculation.
2PH (Pin 31)
This pin is used to choose between single or two phase
operation. Tying this pin to VCC allows for 2-Phase operation.
Tying the 2PH pin to GND causes the controller to operate in
a single phase mode.
REF0 and REF1 (Pins 30, 21)
These pins make up the 2-Bit input that selects the fixed DAC
reference voltage. These pins respond to TTL logic
thresholds. The ISL6310 decodes these inputs to establish
one of four fixed reference voltages; see Table 1 for
correspondence between REF0 and REF1 inputs and
reference voltage settings.
