FAN53418  
Synchronous DC-DC MOSFET Driver  
Features  
General Description  
• Drives N-channel High-Side and Low-Side MOSFETs in  
a synchronous buck configuration  
• Internal Adaptive “Shoot-Through” Protection  
• High Switching Frequency (> 500kHz)  
– 30ns Output Rise/Fall Times w/3000pF load  
– 20ns Propagation Delay  
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.  
• 12V High-Side and 12V Low-Side Drive  
• OD input for Output Disable – allows for synchronization  
with PWM controller  
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.  
• SOIC-8 Package  
Applications  
• Multi-phase VRM/VRD regulators for Microprocessor  
Power  
• High Current/High Frequency DC/DC Converters  
• High Power Modular Power Supplies  
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.
