FDMF6708N Datasheet | Fairchild Semiconductor

Features - Over 93% Peak-Efficiency - High-Current Handling: 50 A - High-Performance PQFN Copper-Clip Package - 3-State 5 V PWM Input Driver - Automatic Diode Emulation (Skip Mode) enabled through ZCD_EN# Input - Thermal Warning Flag for Over-Temperature Condition - Driver Output Disable Function (DISB# Pin) - Internal Pull-Up and Pull-Down for ZCD_EN# and DISB# Inputs, Respectively - Fairchild Power Trench® Technology MOSFETs for Clean Voltage Waveforms and Reduced Ringing - Fairchild Sync FET™ (Integrated Schottky Diode) Technology in Low-Side MOSFET - Integrated Bootstrap Schottky Diode - Adaptive Gate Drive Timing for Shoot-Through Protection - Under-Voltage Lockout (UVLO) - Optimized for Switching Frequencies up to 1MHz - Low-Profile SMD Package - Fairchild Green Packaging and Ro HS pliance - Based on the Intel® 4.0 Dr MOS Standard Description The XS™ Dr MOS family is Fairchild’s next-generation, fully optimized, ultra-pact, integrated MOSFET plus driver power stage solution for high-current, highfrequency, synchronous buck DC-DC applications. The FDMF6708N integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-pact 6x6 mm package. With an integrated approach, the plete switching power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). XS™ Dr MOS uses Fairchild's high-performance Power Trench® MOSFET technology, which dramatically reduces switch ringing, eliminating the need for snubber circuit in most buck converter applications. A driver IC with reduced dead times and propagation delays further enhances the performance. A thermal warning function warns of a potential over-temperature situation. The FDMF6708N also incorporates a Zero Cross Detect (ZCD_EN#) for improved light-load efficiency. The FDMF6708N also provides a 3-state 5 V PWM input for patibility with a wide range of PWM controllers. Applications - Notebook puters - High-Performance...
