ADP3120JRZ中文资料亚德诺数据手册PDF规格书

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
