GENERAL DESCRIPTION
The ADP3418 is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a nonisolated, synchronous, buck power converter. Each of the drivers is capable of driving a 3000 pF load with 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 ADP3418 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs. The OD pin shuts off both the high side and the low-side MOSFETs to prevent rapid output capacitor discharge during system shutdowns.

FEATURES
All-in-one synchronous buck driver
Bootstrapped high-side drive
1 PWM signal generates both drives
Anticross-conduction protection circuitry
Output disable control turns off both MOSFETs to float the output per Intel® VR 10 and AMD Opteron™ specifications

APPLICATIONS
Multiphase desktop CPU supplies
Single-supply synchronous buck converters
