ADP3418KRZ-REEL

Gate Driver Overview

The ADP3418KRZ-REEL is a dual, high-voltage MOSFET driver optimized for driving two N-channel MOSFETs in nonisolated synchronous buck power converters. It operates with a supply voltage range of 4.15V to 13.2V and supports logic input levels of 0.8V (VIL) and 2.8V (VIH). Each driver channel can drive a 3000 pF load with a transition time of 30 ns. The device features a bootstrapped high-side drive capability and includes an output disable pin to shut off both MOSFETs.

Gate Driver Feature Summary

• Generates both high-side and low-side drives from a single PWM signal
• Includes anticross-conduction protection circuitry to prevent shoot-through current
• Features an output disable control that turns off both MOSFETs to float the output

Gate Driver Applications

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

Gate Driver Procurement Notes

Verify the manufacturer designation carefully, as this component originates from Analog Devices but is distributed by onsemi. Confirm the specific suffix indicates the reel packaging format. Ensure the datasheet revision matches your design requirements. Cross-reference the pinout and electrical characteristics with the official documentation provided by the distributor or manufacturer to avoid integration errors.

Gate Driver Selection Notes

Select this component for applications requiring a compact solution for synchronous buck conversion without isolation. It is suitable where overlapping drive protection is critical to prevent shoot-through. Consider the 12V bootstrap limit and the specific logic voltage thresholds when interfacing with microcontrollers or PWM controllers.

Gate Driver Part Context

This part belongs to the ADP3418 family of dual MOSFET drivers. It is designed specifically for synchronous rectification in DC-DC converters. The KRZ suffix typically denotes the MSOP package variant. The REEL suffix indicates it is supplied in tape and reel packaging for automated assembly processes.

Gate Driver Replacement Considerations

Check for direct substitutes within the same driver family. Verify compatibility with existing PCB footprints and thermal requirements. Ensure replacement parts support the same bootstrap voltage and logic input specifications.
