The Clean Switching Waveforms with Minimal Ringing FDMF6840C integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a High-Current Handling thermally enhanced, ultra-compact 6x6 mm package. Features With an integrated approach, the complete switching power stage is optimized with regard to driver and Over 93% Peak-Efficiency MOSFET dynamic performance, system inductance, and power MOSFET R . XS DrMOS uses High-Current Handling: 50 A DS(ON) Fairchild s high-performance PowerTrench MOSFET High-Performance PQFN Copper-Clip Package technology, which dramatically reduces switch ringing, eliminating the need for snubber circuit in most buck 3-State 3.3 V PWM Input Driver converter applications. Skip-Mode SMOD (Low-Side Gate Turn Off) Input A driver IC with reduced dead times and propagation Thermal Warning Flag for Over-Temperature delays further enhances the performance. A thermal Condition warning function warns of a potential over-temperature situation. The FDMF6840C also incorporates a Skip Driver Output Disable Function (DISB Pin) Mode (SMOD ) for improved light-load efficiency. The Internal Pull-Up and Pull-Down for SMOD and FDMF6840C also provides a 3-state 3.3 V PWM input DISB Inputs, Respectively for compatibility with a wide range of PWM controllers.
