The Clean Switching Waveforms with Minimal Ringing FDMF6824B integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a High-Current Handling thermally enhanced, ultra-compact 6x6mm 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 DS(ON) High-Current Handling: 55 A 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 5 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 FDMF6824B 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 FDMF6824B also provides a 3-state 5 V PWM input for DISB Inputs, Respectively compatibility with a wide range of PWM controllers.
