ADP3419

Dual Bootstrapped, High

Voltage MOSFET Driver

with Output Disable

The ADP3419 is a dual MOSFET driver optimized for driving two

N-channel switching MOSFETs in nonisolated synchronous 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.

MSOP−10

CASE 846AC

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.
