ADP3418 Dual Bootstrapped, 12 V Mosfet Driver with Output Disable SOP-8

Description:

The ADP3418 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 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 ADP3418 includes overlapping drive protection to prevent shoot-through current in the external MOSFETs. The OD pin shuts off both the highside and the low-side MOSFETs to prevent rapid output capacitor discharge during system shutdowns.
The ADP3418 is specified over the commercial temperature range of 0°C to 85°C and is available in an 8-lead SOIC package.

Features:

• All-in-one synchronous buck driver
• Bootstrapped high-side drive
• 1 PWM signal generates both drives
• Anticross-conduction protection circuitry
• Output disable control turns off both MOSFETs to float the output per Intel® VR 10 and AMD Opteron(TM) specifications

Application:

• Multiphase desktop CPU supplies
• Single-supply synchronous buck converters

Package included:

• 1 x ADP3418 Dual Bootstrapped, 12 V Mosfet Driver with Output Disable SOP-8
