Overview

The ADP3611 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 accommodate the high voltage slew rate associated with floating high-side gate drivers. An internal synchronous MOSFET is used to replace an external bootstrap Schottky diode. This allows a larger high side gate voltage for increased efficiency.
