GENERAL DESCRIPTION

The ADP3412 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

ADP3412 includes overlapping drive protection (ODP) to pre-

vent shoot-through current in the external MOSFETs.
