FDMF6707C: Extra-Small, High-Performance, High-Frequency DrMOS Module

The XS™ DrMOS family is Fairchild’s next-generation, fully optimized, integrated MOSFET plus driver power stage solution for high-current, high-frequency, synchronous buck DC-DC applications. The FDMF6707C 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.

A new driver IC with reduced dead times and propagation delays further enhances performance. A thermal warning function indicates potential overtemperature situations. FDMF6707C also incorporates features such as Skip Mode (SMOD) for improved lightload efficiency, along with a three-state 5V PWM input for compatibility with a wide range of PWM controllers.
