FAN5009 Dual Bootstrapped 12V MOSFET Driver • Drives N-channel High-Side and Low-Side MOSFETs in a synchronous buck • 12V High-Side and 12V Low-Side Drive • Internal Adaptive “Shoot-Through” Protection • Integrated Bootstrap Diode for High-Side Drive • Fast rise and fall times • Switching Frequency Up to 500kHz • OD input for Output Disable allows for synchronization with PWM controller • SOIC-8 Package • Available in low thermal resistance MLP package • Multi-phase VRM/VRD regulators for Microprocessor Power • High Current/High Frequency DC/DC Converters • High Power Modular Supplies The FAN5009 is a dual, high frequency MOSFET driver, designed to drive N-Channel power MOSFETs in a buck converter. These drivers, combined with a Fairchild Multi-Phase PWM controller and power MOSFETs, form a complete core voltage regulator solution for advanced microprocessors. The FAN5009 drives the upper and lower MOSFET gates of a synchronous buck regulator to 12VGS. The upper gate drive includes an integrated boot diode and requires only an external bootstrap capacitor CBOOT . The output drivers in the FAN5009 have the capacity to switch power MOSFETs at frequencies up to 500kHz. The circuit’s adaptive shoot-through protection prevents the MOSFETs from conducting simultaneously. The FAN5009 is rated for operation from 0°C to +85°C and is available in low-cost SOIC-8 or MLP packages.
