ADP3415中文资料Dual MOSFET Driver with Bootstrapping数据手册ONSEMI规格书

描述 Description

The ADP3415 is a dual MOSFET driver optimized for driving two N-channel FETs that are the two switches in the nonisolated synchronous buck power converter topology. Each driver size is optimized for performance in notebook PC regulators for CPUs in the 20 A range. The high-side driver can be bootstrapped atop the switched node of the buck converter as needed to drive the upper switch and is designed to accommodate the high voltage slew rate associated with high performance, high frequency switching. The ADP3415 features an overlapping protection circuit (OPC); undervoltage lockout (UVLO) that holds the switches off until the driver is assured of having sufficient voltage for proper operation; a programmable transition delay; and a synchronous drive disable pin. The quiescent current, when the device is disabled, is less than 100 µA.
