Pinout identical, but electrical specifications, package and temperature range may vary
The ADP3120 is a dual, high voltage MOSFET driver optimized for driving two N-channel MOSFETs, the two switches in a non-isolated synchronous buck power converter. Each of the drivers is capable of driving a 3000 pF load with a 45 ns propagation delay and a 25 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 ADP3120 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 ADP3120 is specified over the commercial temperature range of 0°C to 85°C and is available in 8-lead SOIC and 8-lead LFCSP packages.
