Overview
FDMF6821B — Extra-Small, High-Performance, High-Frequency DrMOS Module October 2012 FDMF6821B — Extra-Small, High-Performance, High-Frequency DrMOS Module Benefits                      Ultra-Compact 6x6 mm PQFN, 72% Space-Saving Compared to Conventional Discrete Solutions Fully Optimized System Efficiency Clean Switching Waveforms with Minimal Ringing High-Current Handling Description The XS™ DrMOS family is Fairchild’s next-generation, fully optimized, ultra-compact, integrated MOSFET plus driver power stage solution for high-current, highfrequency, synchronous buck DC-DC applications.
The FDMF6821B integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode into a thermally enhanced, ultra-compact 6x6 mm package.
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 FDMF6821B also incorporates a Skip Mode (SMOD#) for improved light-load efficiency.
The FDMF6821B also provides a 3-state 3.
3 V PWM input for compatibility with a wide range of PWM controllers.
Features Over 93% Peak-Efficiency High-Current Handling: 55 A High-Performance PQFN Copper-Clip Package 3-State 3.
3 V PWM Input Driver Skip-Mode SMOD# (Low-Side Gate Turn Off) Input Thermal Warning Flag for Over-Temperature Condition Driver Output Disable Function (DISB# Pin) Internal Pull-Up and Pull-Down for SMOD# and DISB# Inputs, Respectively Fairchild PowerTrench® Technology MOSFETs for Clean Voltage Waveforms and Reduced Ringing Fairchild SyncFET™ (Integrated Schottky Diode) Technolog...
