1. Add “-T*” suffix for tape and reel. Please refer to
2. Intersil Pb-free plus anneal products employ special Pb-free material sets; molding compounds/die attach materials and 100% matte tin plate
3. For Moisture Sensitivity Level (MSL), please see device information page for ISL6267. For more information on MSL please see tech brief TB363.
PIN NUMBER
termination finish, which are 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.

MARKING
PART
Connect an MLCC capacitor across the BOOT1_NB and the PH1_NB pins. The boot capacitor is charged
through an internal boot diode connected from the VCCP pin to the BOOT1_NB pin, each time the
PH1_NB pin drops below VCCP minus the voltage dropped across the internal boot diode.
Program pin for setting output voltage offset for Northbridge VR.
Thermistor input to VR_HOT circuit to monitor Northbridge VR temperature.
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.
Output voltage sense return pin for the Northbridge controller. Connect to the -sense pin of the
microprocessor die.
Output voltage sense pin for the Northbridge controller. Connect to the +sense pin of the microprocessor
die.
Individual current sensing for Channel 2 of the Northbridge VR. When ISEN2 is pulled to 5V VDD, the
controller will disable Channel 2 and the Northbridge VR will run single-phase.
Individual current sensing for Channel 1 of the Northbridge VR.
Signal common of the IC. Unless otherwise stated, signals are referenced to the GND pin.
