Description

The XS™ DrMOS family is Fairchild’s next-generation,

fully optimized, ultra-compact, integrated MOSFET plus

driver power stage solutions for high-current, high-

frequency, synchronous buck DC-DC applications. The

FDMF6706C integrates a driver IC, two power

MOSFETs, and a bootstrap Schottky diode into a

thermally enhanced, ultra-compact 6x6 mm PQFN

package.

With an integrated approach, the complete switching

power stage is optimized with regards 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 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 has been included

to warn of a potential over-temperature situation. The

FDMF6706C also incorporates features, such as Skip

Mode (SMOD), for improved light-load efficiency along

with a 3-state 5 V PWM input for compatibility with a

wide range of PWM controllers.

Applications

 High-Performance Gaming Motherboards

 Compact Blade Servers, V-Core and Non-V-Core

DC-DC Converters

 Desktop Computers, V-Core and Non-V-Core

DC-DC Converters

 Workstations

 High-Current DC-DC Point-of-Load (POL)

Converters

 Networking and Telecom Microprocessor Voltage

Regulators

 Small Form-Factor Voltage Regulator Modules
