FDMF6707B

The XS DrMOS family is Fairchild’s next-generation, fully optimized, ultra-compact, integrated MOSFET plus driver power stage solution for high-current, high-frequency, synchronous buck DC-DC applications. The FDMF6707B 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 for 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 snubber circuit in most buck converter applications. A new driver IC with reduced dead times and propagation delays further enhances performance. A thermal warning function warns of potential over-temperature situations. FDMF6707B also incorporates features such as Skip Mode (SMOD) for improved light-load efficiency, along with a 3-state 3.3V PWM input for compatibility with a wide range of PWM controllers.
