Synchronous DC-DC MOSFET Driver

The FAN5109B is a dual, high-frequency MOSFET driver, specifically designed to drive N-channel Power MOSFETs in a synchronous-rectified buck converter. These drivers, combined with a Fairchild multi-phase pulse-width-modulated (PWM) controller and Power MOSFETs form a complete core voltage Regulator solution for advanced Microprocessors
The FAN5109B drives the upper and lower MOSFET Gates of a synchronous buck Regulator to 12VGS. The output drivers have the capacity to efficiently Switch Power MOSFETs at frequencies above 500KHz. The circuit's adaptive shoot-through protection prevents both MOSFETs from conducting simultaneously.
The FAN5109B is rated for operation from 0C to +85C and is available in a low-cost SOIC-8 package.
