GENERAL DESCRIPTION
The ADP3415 is a dual MOSFET driver optimized for driving
two N-channel FETs that are the two switches in the noniso-
lated synchronous buck power converter topology. The driver
sizes are each optimized for performance in notebook PC regula-
tors for CPUs in the 20-amp 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 accommo-
date the high voltage slew-rate associated with high-performance
high-frequency switching. The ADP3415 has several 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 mA.
The ADP3415 is available in a 10-lead MSOP package.
