ADP3417中文资料亚德诺数据手册PDF规格书

GENERAL DESCRIPTION

The ADP3417 is a dual 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 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 ADP3417 includes overlapping drive protection (ODP) to prevent shoot-through current in the external MOSFETs.

The ADP3417 is specified over the commercial temperature range of 0°C to 70°C and is available in an 8-lead SOIC package.
