GENERAL DESCRIPTION

The ADP3418 is a dual high voltage MOSFET driver optimized

for driving two N-channel MOSFETs, which are the two switches

in a nonisolated synchronous buck power converter. Each of the

drivers is capable of driving a 3000 pF load with a 20 ns propa-

gation delay and a 30 ns transition time. One of the drivers can

be bootstrapped and is designed to handle the high voltage slew

rate associated with floating high-side gate drivers. The ADP3418

includes overlapping drive protection to prevent shoot-through

current in the external MOSFETs. The OD pin shuts off both

the high-side and the low-side MOSFETs to prevent rapid output

capacitor discharge during system shutdown.

The ADP3418 is specified over the commercial temperature

range of 0°C to 85°C and is available in a thermally enhanced

8-lead SOIC package.
