FDMF6706B - Extra-Small, High-Performance, High- Frequency Dr MOS Module Benefits

Description

 Ultra-Compact 6x6mm PQFN, 72% Space-Saving The XS™ Dr MOS family is Fairchild’s next-generation, Compared to Conventional Discrete Solutions fully optimized, ultra-compact, integrated MOSFET plus

driver power stage solution for high-current, high-

 Fully Optimized System Efficiency

frequency, synchronous buck DC-DC applications. The

 Clean Switching Waveforms with Minimal Ringing FDMF6706B integrates a driver IC, two power MOSFETs,

and a bootstrap Schottky diode into a thermally

 High-Current Handling

enhanced, ultra-compact 6x6mm PQFN package.

Features

With an integrated approach, the complete switching power stage is optimized for driver and MOSFET

 Over 93% Peak-Efficiency

dynamic performance, system inductance, and power  High-Current Handling of 45A MOSFET RDS(ON). XS™ Dr MOS uses Fairchild's high- performance Power Trench® MOSFET technology,

 High-Performance PQFN Copper-Clip Package

which dramatically reduces switch ringing, eliminating  3-State 3.3V PWM Input Driver the snubber circuit in most buck converter applications.  Skip-Mode SMOD# (Low-Side Gate Turn Off) Input A new driver IC with reduced dead times and propagation delays further enhances performance. A

 Thermal Warning Flag for Over-Temperature

thermal warning function warns of potential over-
