DESCRIPTION
Northbridge VR error amplifier output. A resistor from COMP_NB to GND sets the Northbridge VR offset
voltage and is used to set the switching frequency for the Core VR and Northbridge VR.
Output voltage feedback to the inverting input of the Northbridge controller error amplifier.
Output voltage sense pin for the Northbridge controller. Connect to the +sense pin of the microprocessor
die.
Inverting input of the transconductance amplifier for current monitor and load line of the Northbridge VR.
Non-inverting input of the transconductance amplifier for current monitor and load line of the
Northbridge VR.
Signal common of the IC. All signals are referenced to the GND pin.

NOTES:
1. Add “-T*” suffix for tape and reel. Please refer to TB347 for details on reel specifications.
2. These Intersil Pb-free plastic packaged products employ special Pb-free material sets, molding compounds/die attach materials, and 100% matte
tin plate plus anneal (e3 termination finish, which is RoHS compliant and compatible with both SnPb and Pb-free soldering operations). Intersil
Pb-free products are MSL classified at Pb-free peak reflow temperatures that meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL62771 . For more information on MSL please see tech brief TB363 .
