Description
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
FDMF6707V integrates a driver IC, two power MOSFETs,
and a bootstrap Schottky diode into a thermally
enhanced, ultra-compact 6x6mm PQFN package.
With an integrated approach, the complete switching
power stage is optimized for 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 snubber circuit in most buck converter applications.
A new driver IC, with reduced dead times and
propagation delays, further enhances performance. An
internal 12V to 5V linear regulator enables the
FDMF6707V to operate from a single 12V supply. A
thermal warning function warns of potential over-
temperature situations. FDMF6707V also incorporates
features such as Skip Mode (SMOD) for improved light-
load efficiency, along with a 3-state 3.3V PWM input for
compatibility with a wide range of PWM controllers.
