Functional Pin Description
UGATE (Pin 1)
Connect UGATE pin to the synchronous PWM
converter’s upper MOSFET gate. This pin provides
the gate drive for the upper MOSFET.
converter’s MOSFET source. This pin is used to moni-
tor the voltage drop across the MOSFET for over-cur-
rent protection.
PGOOD (Pin 5)
VCC (Pin 2)
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.
GATE (Pin 3)
Connect GATE pin to the standard BUCK PWM
converter’s MOSFET gate. This pin provides the gate
drive for the MOSFET.
PHASE2 (Pin 4)
Connect the PHASE2 pin to the standard BUCK PWM
PGOOD is an open collector output used to indicate
the status of the output voltages. This pin is pulled
low when the synchronous regulator output is not within
10% of the reference voltage or the other output is
below under-voltage thresholds.
NC (Pin 10, 13)
No Connection.
