ADP3110KRZ

双自举，与输出禁用12 V MOSFET驱动器 Dual Bootstrapped, 12 V MOSFET Driver with Output Disable

GENERAL DESCRIPTION

The ADP3110 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 pFload with a

25 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 ADP3110 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
