FDMF6705B - Extra-Small, High-Performance, High-
Frequency DrMOS Module
Benefits
Description

?
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
The XS? DrMOS family is Fairchild’s next-generation,
fully optimized, ultra-compact, integrated MOSFET plus
driver power stage solution for high-current, high-
frequency, synchronous buck DC-DC applications. The
FDMF6705B integrates a driver IC, two power MOSFETs,
and a bootstrap Schottky diode into a thermally
enhanced, ultra-compact 6x6 mm PQFN package.
Features
? Over 93% Peak-Efficiency
? High-Current Handling of 40 A at 12 V IN
? High-Current Handling of 38 A at 19 V IN
With an integrated approach, the complete switching
power stage is optimized with regards to driver and
MOSFET dynamic performance, system inductance,
and power MOSFET R DS(ON). XS? DrMOS uses
Fairchild's high-performance PowerTrench ? MOSFET
technology, which dramatically reduces switch ringing,

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
eliminating the need for a snubber circuit in most buck
converter applications.
A new driver IC with reduced dead times and
propagation delays further enhances the performance of
this part. A thermal warning function warns of a potential
over-temperature situation. The FDMF6705B also
incorporates features, such as Skip Mode (SMOD), for
improved light-load efficiency, along with a three-state
3.3 V PWM input for compatibility with a wide range of
PWM controllers.
