Fairchild Semiconductor’s Generation II XS™ DrMOS Devices Offer 94% Efficiency in 6mm x 6mm Form Factor

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 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 highperformance PowerTrench® MOSFET technology, which dramatically reduces switch ringing, eliminating the snubber circuit in most buck converter applications.
