Product Summary

The ADP3110A is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a nonisolated synchronous buck power converter. The device is capable of driving a 3000 pF load with a 25 ns propagation delay and a 30 ns transition time. One of the ADP3110A can be bootstrapped and is designed to handle the high voltage slew rate associated with floating high-side gate drivers. The ADP3110A includes overlapping drive protection to prevent shoot-through current in the external MOSFETs. The device is specified over the commercial temperature range of 0 to 85℃ and is available in an 8-lead SOIC_N or an 8-lead LFCSP_VD package. The applications of the ADP3110A include Multiphase desktop CPU supplies and Single-supply synchronous buck converters.
