onsemi FDMF6706C

The XS™ DrMOS family is next-generation, fully optimized, ultra-compact, integrated MOSFET plus driver power stage solutions for high-current, high-frequency, synchronous buck DC-DC applications. The FDMF6706C integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact 6x6 mm 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 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 FDMF6706C also incorporates features, such as Skip Mode (SMOD), for improved light-load efficiency along with a 3-state 5 V PWM input for compatibility with a wide range of PWM controllers.
