FAN53418

The FAN53418 is a high frequency, dual MOSFET driver specifically designed to drive two power N-Channel MOSFETs in a synchronous rectified buck converter. These drivers combined with a FAN53168 Multi-Phase Buck PWM controller and power MOSFETs form a complete core voltage regulator solution for advanced microprocessors.
The FAN53418 drives both the upper and lower gates in a synchronous rectifier to +12V.  The upper gate drive imple-ments bootstrapping with only an external capacitor and diode required.  This reduces implementation complexity and allows the use of higher performance, cost effective,
N-Channel MOSFETs.
The output drivers in the FAN53418 have the capacity to efficiently switch power MOSFETs at frequencies over 500kHz.  Each driver is capable of driving a 3000pF load with a ~20ns propagation delay and ~30ns transition time.  Adaptive shoot-through protection is integrated to prevent both MOSFETs from conducting simultaneously. Addition-ally an Output Disable function is included to synchronize the driver with the PWM controller.  The FAN53418 is rated for operation from 0°C to +85°C and is available in a low-cost SOIC-8 package.
