FDMF6705V - Extra-Small, High-Performance, High- Frequency Dr MOS Module

Benefits Description The XS™ Dr MOS family is Fairchild’s next-generation,

 Single 12V Input Power Supply Operation

fully optimized, ultra-compact, integrated MOSFET

 Ultra-Compact 6x6mm PQFN, 72% Space-Saving plus driver power stage solutions for high-current, Compared to Conventional Discrete Solutions high-frequency, synchronous buck DC-DC

 Fully Optimized System Efficiency applications. The FDMF6705V integrates a driver IC, two power MOSFETs, and a bootstrap Schottky diode

 Clean Switching Waveforms with Minimal Ringing

into a thermally enhanced, ultra-compact 6x6mm  High-Current Handling PQFN package. Features With an integrated approach, the complete switching power stage is optimized with regards to driver and

 Over 93% Peak-Efficiency

MOSFET dynamic performance, system inductance,  High-Current Handling of 43A and Power MOSFET RDS(ON). XS™ Dr MOS uses Fairchild's high-performance Power Trench® MOSFET

 High-Performance PQFN Copper Clip Package

technology, which dramatically reduces switch ringing,

 3-State 5V PWM Input Driver eliminating the need for a snubber circuit in most buck

converter applications.

 Shorter Propagation Delays than FDMF6704V

 Shorter Dead Times than FDMF6704V A new driver IC with reduced dead times and propagation delays further enhances the performance of

 Skip-Mode SMOD# (Low-Side Gate Turn Off) Input

this part. A thermal warning function has been included  Thermal Warning Flag for Over-Temperature to warn of a potential over-temperature situation. The Condition FDMF6705V also incorporates features, such as Skip Mode (SMOD), for improved light-load efficiency along

 Driver Output Disable Function (DISB# Pin)

with a 3-state PWM input for compatibility with a wide

 Internal Pull-Up and Pull-Down for SMOD# and range of PWM controllers. DISB# Inputs, Respectively
