GENERAL DESCRIPTION  
GENERAL APPLICATION CIRCUIT  
The ADP3419 is a dual MOSFET driver optimized for driving  
two N-channel switching MOSFETs in nonisolated synchro-  
nous 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.

CROWBAR DRVL  
The ADP3419 includes an anticross-conduction protection  
circuit, undervoltage lockout to hold the switches off until the  
driver has sufficient voltage for proper operation, a crowbar  
input that turns on the low-side MOSFET independently of the  
input signal state, and a low-side MOSFET disable pin to  
provide higher efficiency at light loads. The SD pin shuts off  
both the high-side and the low-side MOSFETs to prevent rapid  
output capacitor discharge during system shutdown.

The ADP3419 is specified over the extended commercial  
temperature range of 0°C to 100°C and is available in a 10-lead  
MSOP package.
