Dual Synchronous Driver

Overview

The ADP3419 is a dual MOSFET driver optimized for driving two N-channel switching MOSFETs in nonisolated synchronous buck power converters used to power CPUs in portable computers. The driver impedances have been chosen to provide optimum performance in multiphase regulators at up to 25 A per phase. The high-side driver can be bootstrapped relative to the switch node of the buck converter and is designed to accomodate the high voltage slew rate associated with floating high-side gate drivers.

Applications

CPU core power converters
Multiphase CPU supplies
Single-supply synchronous buck converters
Nonsynchronous-to-synchronous drive conversion

End Products

Desktop computers
Notebook computers

Features

All in one synchronous buck converter
One PWM generates both drives
Anti cross-conduction protection circuitry
Output Disable function
Synchronous overdrive control
Crowbar control
