GENERAL DESCRIPTION

The ADP3410 is a dual MOSFET driver optimized for driving two N-channel FETs that are the two switches in the nonisolated synchronous buck power converter topology. Each of the drivers is capable of driving a 3000 pF load with a 20 ns propagation 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 ADP3410 has several protection features: overlapping drive prevention (ODP), undervoltage lockout (UVLO) with performance specified at very low VCC levels, and overvoltage protection (OVP) that can be used to monitor either the input or output.
