GENERAL DESCRIPTION
The ADP3414 is a dual MOSFET driver optimized for driving
two N-channel MOSFETs which are the two switches in a
nonisolated synchronous buck power converter. Each of the
drivers is capable of driving a 3000 pF load with a 20 ns propa-
gation delay and a 30 ns transition time. One of the drivers can
be bootstrapped, and is designed to handle the high-voltage
slew rate associated with
“
floating
”
high-side gate drivers.
The ADP3414 includes overlapping drive protection (ODP)
to prevent shoot-through current in the external MOSFETs.
The ADP3414 is specified over the commercial temperature
range of 0
°
C to 70
°
C and is available in an 8-lead SOIC package.
