Dual Bootstrapped MOSFET Driver; ? All-In-One Synchronous Buck Driver\n? Bootstrapped High Side Drive\n? One PWM Signal Generates Both Drives\n? Anticross-Conduction Protection Circuitry;

GENERAL DESCRIPTION\nThe 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 propagation 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 ADP3417 includes overlapping drive protection (ODP) to prevent shoot-through current in the external MOSFETs.\nThe ADP3417 is specified over the commercial temperature range of 0°C to 70°C and is available in an 8-lead SOIC package.FEATURES\n?
