GENERAL DESCRIPTION
The ADP3418 is a dual, high voltage MOSFET driver optimized
for driving two N-channel MOSFETs, the two switches in a
nonisolated, synchronous, buck power converter. Each of the
drivers is capable of driving a 3000 pF load with 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 shutdowns.
The ADP3418 is specified over the commercial temperature
range of 0°C to 85°C, and is available in an 8-lead SOIC
package.
