GENERAL DESCRIPTION  
The ADP3417 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 floatinghigh side gate drivers.  
The ADP3417 includes overlapping drive protection (ODP)  
to prevent shoot-through current in the external MOSFETs.
