FDMF6820C Datasheet PDF - Fairchild

●The FDMF6820C is a fully optimized ultra-compact integrated MOSFET plus Driver Power Stage Solution for high-current, high-frequency, synchronous buck DC-DC applications. The FDMF6820C integrates a driver IC, two power MOSFETs and a bootstrap Schottky diode. With an integrated approach, the complete switching power stage is optimized with regard 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 snubber circuit in most buck converter applications. A driver IC with reduced dead times and propagation delays further enhances the performance. A thermal warning function warns of a potential over-temperature situation. The FDMF6820C also provides a 3-state 3.3V PWM input for compatibility with a wide range of PWM controllers.
