FAN53418 - Fairchild Semiconductor

FAN53418 Synchronous DC-DC MOSFET Driver

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 l.
