onsemi ADP3110
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. The ADP3110 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs.| Part No. | ADP3110 |

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 specificationAPPLICATIONS
Multiphase desktop CPU supplies Single-supply synchronous buck converters Dual Bootstrapped, 12 V MOSFET Driver with Output Disable ADP3110GENERAL DESCRIPTION
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 OD 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.
