Dual Bootstrapped 12 V MOSFET

Driver with Output Disable

ADP3120

FEATURES

GENERAL DESCRIPTION

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

The ADP3120 is a dual, high voltage MOSFET driver optimized

for driving two N-channel MOSFETs, the two switches in a non-

isolated 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.

APPLICATIONS

Multiphase desktop CPU supplies

Single-supply synchronous buck converters

The

pin shuts off both the high-side and the low-side

MOSFETs to prevent rapid output capacitor discharge during

system shutdown.

The ADP3120 is specified over the commercial temperature

range of 0°C to 85°C and is available in 8-lead SOIC and 8-lead

LFCSP packages.
