Datasheet Summary
Dual Bootstrapped, 12 V
MOSFET Driver with Output
Disable
The ADP3121 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 driver is capable of driving a 3000 pF load with a 20 ns propagation delay and a 15 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 ADP3121 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...
