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 propagation delay and a 30 ns transition time. One of the drivers can be bootstrapped, and is designed to handle the high-voltage lew rate associated with "floating" high-side gate drivers. The ADP3412 includes overlapping drive protection (ODP) to prevent shoot-through current in the external MOSFETs.
