The Fully Optimized System Efficiency FDMF6833C integrates a driver IC, two power Clean Switching Waveforms with Minimal Ringing MOSFETs, and a bootstrap Schottky diode into a High-Current Handling thermally enhanced, ultra-compact 6x6 mm package. With an integrated approach, the complete switching Features power stage is optimized with regard to driver and MOSFET dynamic performance, system inductance, Over 93% Peak-Efficiency and power MOSFET R . XS DrMOS uses DS(ON) High-Current Handling: 50 A Fairchild s high-performance PowerTrench MOSFET technology, which dramatically reduces switch ringing, High-Performance PQFN Copper-Clip Package 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 delays further enhances the performance. A thermal Thermal Warning Flag for Over-Temperature warning function warns of a potential over-temperature Condition situation. The FDMF6833C also incorporates a Skip Driver Output Disable Function (DISB Pin) Mode (SMOD ) for improved light-load efficiency. The FDMF6833C also provides a 3-state 5 V PWM input for Internal Pull-Up and Pull-Down for SMOD and compatibility with a wide range of PWM controllers.
