PWRGOOD
VCORE and NB Power Good.
It is an open-drain output set free after SS as long as both the voltage planes are
within specifications. Pull-up to 3.3V (typ) or lower, if not used it can be left floating.
When in PVI mode, it monitors the CORE section only.

NB_BOOT
NB section high-side driver supply.
This pin supplies the high-side floating driver. Connect through CBOOT capacitor to the
NB_PHASE pin.
See Section 10 for guidance in designing the capacitor value.
37
NB_UGATE
NB section high-side driver output.
Connect to NB section high-side MOSFET gate. A small series resistor may help in
reducing NB_PHASE pin negative spike as well as cooling the device.
38
NB_PHASE
NB section high-side driver return path.
Connect to the NB section high-side MOSFET source.
This pin is also monitored for the adaptive dead-time management.
39
BOOT2
CORE section, phase 2 high-side driver supply.
This pin supplies the High-Side floating driver. Connect through CBOOT capacitor to
the PHASE2 pin.
See Section 10 for guidance in designing the capacitor value.
40
UGATE2
High-side driver output.
Connect to Phase2 high-side MOSFET gate. A small series resistor may help in
reducing PHASE2 pin negative spike as well as cooling the device.
41
PHASE2
CORE section, phase 2 high-side driver return path. Connect to the Phase2 high-side
MOSFET source.
This pin is also monitored for the adaptive dead-time management.
42
VCCDRV
Supply voltage for low-side embedded drivers.
Operative voltage is flexible from 5V ±5% to 12 ±15%. Filter with 1
μF MLCC to GND.
Do not connect VCC to any voltage greater than VCCDR.

NB_LGATE,
LGATE2,
LGATE1
Low-side driver output.
Connect directly to the low-side MOSFET gate of the related section. A small series
resistor can be useful to reduce dissipated power especially in high frequency
applications.
46
PHASE1
CORE section, phase 1 high-side driver return path. Connect to the phase1 high-side
MOSFET source.
This pin is also monitored for the adaptive dead-time management.
47
UGATE1
High-side driver output.
Connect to phase1 high-side MOSFET gate. A small series resistor may help in
reducing PHASE1 pin negative spike as well as cooling the device.
48
BOOT1
CORE section, phase 1 high-side driver supply.
This pin supplies the high-side floating driver. Connect through CBOOT capacitor to the
PHASE1 pin.
See Section 10 for guidance in designing the capacitor value.
Thermal
PAD
GND
All internal references, logic, and the Silicon substrate are referenced to this pin.
Connect to the PCB GND ground plane by multiple vias to improve heat dissipation.
