DESCRIPTION
Input for the overcurrent detection circuit. The overcurrent setpoint programming resistor
R OCSET connects from this pin to the sense node.
No internal connection. Pin 15 should be connected to the GND pin.
Return current path for the UGATE high-side MOSFET driver. V IN sense input for the R 3
modulator. Inductor current polarity detector input. Connect to junction of output inductor,
High-side MOSFET gate driver output. Connect to the gate terminal of the high-side MOSFET
of the converter.
Positive input supply for the UGATE high-side MOSFET gate driver. The BOOT pin is internally
connected to the cathode of the Schottky boot-strap diode. Connect an MLCC between the
BOOT pin and the PHASE pin.
Input for the IC bias voltage. Connect +5V to the VCC pin and decouple with at least a 1μF
Input for the LGATE and UGATE MOSFET driver circuits. The PVCC pin is internally connected
to the anode of the Schottky boot-strap diode. Connect +5V to the PVCC pin and decouple

NOTES:
1. 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 NiPdAu plate - e4 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 ISL62875 . For more information on MSL please
