| FAN5109B Dual Bootstrapped 12V MOSFET Driver August 2007 FAN5109B Dual Bootstrapped 12V MOSFET Driver Drives N-Channel High-Side and Low-Side MOSFETs in a Synchronous Buck Configuration Enhanced Upgrade to FAN5109 Direct Interface to FAN5029/FAN5182 and Other Compatible PWM Controllers 12V High-Side and 12V Low-Side Drive Internal Adaptive Shoot-Through Protection Fast Rise and Fall Times Switching Frequency Above 500kHz OD Input for Output Disable Allows Synchronization with PWM Controller SOIC-8 Package TTL-Compatible Logic Inputs New 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 0°C to +85°C and is available in a low-cost SOIC-8 package.
