GENERAL DESCRIPTION

The ADP3118 is a dual, high voltage 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 25 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 ADP3118 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.

FEATURES

Optimized for low gate charge MOSFETs

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

Meets CPU VR requirement when used with Analog Devices, Inc. Flex-Mode1 controller

APPLICATIONS

Multiphase desktop CPU supplies

Single-supply synchronous buck converters
