Description
The XS⢠DrMOS family is Fairchildâs next-generation,
fully optimized, ultra-compact, integrated MOSFET plus
driver power stage solution for high-current, high-
frequency, synchronous buck DC-DC applications. The
FDMF6823A integrates a driver IC, two power
MOSFETs, and a bootstrap Schottky diode into a
thermally enhanced, ultra-compact 6x6mm package.
With an integrated approach, the complete switching
power stage is optimized with regard 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 snubber circuit in most buck
converter applications.
A driver IC with reduced dead times and propagation
delays further enhances the performance. A thermal
warning function warns of a potential over-temperature
situation. The FDMF6823A also incorporates a Skip
Mode (SMOD#) for improved light-load efficiency. The
FDMF6823A also provides a 3-state 5V PWM input for
compatibility with a wide range of PWM controllers.
Applications
ï§ High-Performance Gaming Motherboards
ï§ Compact Blade Servers, V-Core and Non-V-Core
DC-DC Converters
ï§ Desktop Computers, V-Core and Non-V-Core
DC-DC Converters
ï§ Workstations
ï§ High-Current DC-DC Point-of-Load Converters
ï§ Networking and Telecom Microprocessor Voltage
Regulators
ï§ Small Form-Factor Voltage Regulator Modules
