Dual Bootstrapped, 12 V MOSFET

Driver with Output Disable

ADP3110

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 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 pF load 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.

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 ADP3110 is specified over the commercial temperature

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

package.
