Functional Pin Description (Cont.)
GND (Pin 17)
VSEN1 (Pin 22).
Signal ground for the IC. All voltage levels are
measured with respect to this pin.
GATE3 (Pin 18)
This pin is connected to the PWM converter’s output
voltage . The PGOOD and OVP comparator circuits
use this signal to report output voltage status and for
over-voltage protection .
Connect this pin to the gate of an external MOSFET.
This pin provides the drive for the 1.5V regulator’s
pass transistor.
FB3 (Pin 19)
PGND (Pin 24)
This is the power ground connection . Tie the syn-
chronous PWM converter’s lower MOSFET source
to this pin .
Connect this pin to the output of the 1.5V linear
regulator. This pin is monitored for under-voltage
events.
FB1 (Pin21)
LGATE (Pin 25)
Connect LGATE to the PWM converter’s lower
MOSFET gate . This pin provides the gate drive for
the lower MOSFET .
This pin provides the feedback for the synchronous
switching regulator . Typically this pin can be con-
nected directly to the output of the switching regula-
tor . However , a resistor driver is recommended to
be connected from this pin to vout1 and GND to ad-
just the output voltage for any drop in the output volt-
age that is caused by the trace resistance . The value
of the resistor connected from Vou1 to FB1 must be
less than 100Ω .
UGATE (Pin 27)
Connect UGATE pin to the PWM converter’s upper
MOSFET gate . This pin provides the gate drive for
the upper MOSFET .
V12 (Pin28)
Provide a 12V bias supply for the IC to this pin . This
pin also provides the gate bias charge for all the
MOSFETs controlled by the IC . The voltage at this
pin is monitored for Power-On Reset purposes .
