GENERAL DESCRIPTION
The ADP3120 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 45 ns propagation delay and a 25 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 ADP3120 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.
FEATURES
All-in-one synchronous buck driver
Bootstrapped high-side drive
One PWM signal generates both drives
Anticross-conduction protection circuitry
Output disable control turns off both MOSFETs
to float output per Intel® VRM 10 specification
APPLICATIONS
Multiphase desktop CPU supplies
Single-supply synchronous buck converters
