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.
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.
