GENERAL 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 100µA.
The ADP3415 is specified over the extended commercial
temperature range of 0°C to 100°C and is available in a 10-lead
MSOP package.

NOTESAll limits at temperature extremes are guaranteed via correlation using standard Statistical Quality Control (SQC) methods.Including IBSTQ quiescent current.The signal source driving the pin must have 70 µA (typ) pull-down strength to make a high-to-low transient, and 20 µA (typ) pull-up strength to make a low-to-high
transient. The pin does not represent load (<100 nA) in static low (<0.8 V) and static high (>2.0 V) logic states (see TPC 3.) The pin can be driven with standard
TTL logic level source.Guaranteed by characterization.For propagation delays, tpdh refers to the specified signal going high, tpdl refers to it going low.Propagation delay measured until DRVL begins its transition.The turn-on of DRVL is initiated after IN goes low by either VSW crossing a ~1.6 V threshold or by expiration of tSWTO.

*Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability. Absolute maximum
ratings apply individually only, not in combination. Unless otherwise specified, all
other voltages are referenced to GND.
