BOOT Pin-13 (Input)
The BOOT pin is the input voltage for the high-side MOSFET
gate driver UG. An MLCC capacitor C
BOOT
is connected
between the BOOT pin and the PHASE pin, the return
current path for the UG MOSFET driver. Capacitor C
BOOT
is
charged from the voltage source at the PVCC pin via the
internal diode D
BOOT
each time the PHASE pin drops below
PVCC minus diode D
BOOT
forward voltage drop V
F
.
UG Pin-14 (Output)
The UG pin is the output of the high-side MOSFET gate
driver. Connect to the gate of the high-side MOSFET.
PHASE Pin-15 (Input)
The PHASE pin is the return current path for the UG
MOSFET driver. The PHASE pin also measures the polarity
of the low-side MOSFET drain voltage for the diode
emulation function. Connect the PHASE pin to the node
consisting of the high-side MOSFET source, the low-side
MOSFET drain, and the output inductor. Refer to
Figure 1,
Typical Application Schematic
.
PGOOD Pin-16 (Output)
The PGOOD pin is an open-drain output that is high
impedance when the converter is in regulation, or when the
EN pin is pulled below the falling threshold voltage V
ENTHF
.
The PGOOD pin has three distinct pull-down impedances
that correspond to an OVP fault, OCP/SCP, or UVP and soft-
start. Connect the PGOOD pin to a pull-up resistor.
