FDMF6705V

FDMF6705V - XS™ DrMOS - Extra-Small High-Performance, High-Frequency DrMOS Module March 2011 FDMF6705V – XS™ DrMOS – Extra-Small, HighPerformance, High-Frequency DrMOS Module Benefits Single 12V Input Power Supply Operation 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 solutions for high-current, highfrequency, synchronous buck DC-DC applications. The FDMF6705V 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 with regards to 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 need for a snubber circuit in most buck converter applications. A new driver IC with reduced dead times and propagation delays further enhances the performance of this part. A thermal warning function has been included to warn of a potential over-temperature situation. The FDMF6705V also incorporates features, such as Skip Mode (SMOD), for improved light-load efficiency along with a 3-state PWM input...
