FDMF6706B - Extra-Small, High-Performance, High-Frequency DrMOS Module March 2012 FDMF6706B - Extra-Small, High-Performance, HighFrequency DrMOS Module Benefits                      Ultra-Compact 6x6mm PQFN, 72% Space-Saving Compared to Conventional Discrete Solutions Fully Optimized System Efficiency Clean Switching Waveforms with Minimal Ringing High-Current Handling Description 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 FDMF6706B 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 warns of potential overtemperature situations. FDMF6706B also incorporates features such as Skip Mode (SMOD) for improved lightload efficiency, along with a Three-state 3.3V PWM input for compatibility with a wide range of PWM controllers.
