FDMF6707V: Extra-Small, High-Performance, High-Frequency DrMOS Module

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 FDMF6707V 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. An internal 12V to 5V linear regulator enables the FDMF6707V to operate from a single 12V supply. A thermal warning function warns of potential overtemperature situations. FDMF6707V also incorporates features such as Skip Mode (SMOD) for improved lightload efficiency, along with a 3-state 3.3V PWM input for compatibility with a wide range of PWM controllers.
