The XS™ DrMOS family is Fairchild's next-generation, fully optimized, ultra-compact, integrated MOSFET plus driver power stage solution for high-current, highfrequency, synchronous buck DC-DC applications. The FDMF6705B integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact 6x6mm PQFN package. With an integrated approach, the complete switching power stage is optimized with regards to driver and MOSFET dynamic performance, system inductance, and power MOSFET RDS(ON). XS™ DrMOS uses Fairchild's high-performance PowerTrench® MOSFET technology, which dramatically reduces switch ringing, eliminating the need for a snubber circuit in most buck converter applications.A new driver IC with reduced dead times and propagation delays further enhances the performance of this part. A thermal warning function warns of a potential over-temperature situation. The FDMF6705B also incorporates features, such as Skip Mode (SMOD), for improved light-load efficiency, along with a three-state 3.3V PWM input for compatibility with a wide range of PWM controllers.
