DESCRIPTION
This pin is the upper gate drive supply voltage for the Northbridge controller. Connect an appropriately
sized ceramic bootstrap capacitor between the BOOT_NB and PHASE_NB pins. An internal bootstrap
diode connected to the PVCC pin provides the necessary bootstrap charge.
Upper MOSFET gate signal from Northbridge controller.
Switch node of the Northbridge controller. This pin should connect to the source of the Northbridge
channel upper MOSFET(s).
Lower MOSFET gate signal from Northbridge controller.
The return path of the Northbridge controller lower gate driver. Connect this pin to the source of the lower
MOSFET(s).
Overcurrent protection selection input for the Northbridge controller. A resistor from this pin to
PHASE_NB sets the OC trip point.
Remote Northbridge voltage sense input and return. Connect isolated traces from these pins to the
Northbridge sense points of the processor.
A resistor from this pin to GND programs the switching frequency of the Northbridge controller (for
example, 22.1k ~ 260kHz).
This pin is the output of the Northbridge controller error amplifier.
This pin is the output voltage feedback to the inverting input of the Northbridge controller error amplifier.
The bias supply for the IC’s control circuitry. Connect this pin to a +5V supply and decouple using a quality
0.1μF ceramic capacitor.
Battery supply voltage. It is used for input voltage feed-forward to improve the input line transient
performance.
The bias and reference ground for the IC. The GND connection for the ISL6265C is through the thermal
pad on the bottom of the package.
