High efficiency, high current handling capability and small form
factors are critical to power supply designers when selecting
components for voltage regulator solutions. To meet this need,
Fairchild Semiconductor (NYSE: FCS), a leading global supplier of
high performance power and mobile products, developed its family of
Generation II XS™ DrMOS [Integrated Driver + MOSFET] devices
offering high efficiency and power density to enable designers to
meet specific design needs for various applications.
Generation II XS DrMOS devices, available in a small, 6mm x 6mm
high performance clip PQFN package, feature higher system
efficiency with over 91.5 percent heavy load efficiency at 12Vin,
1Vout, and 25A, and 94 percent peak efficiency. Generation II XS
DrMOS can be operated at a 2MHz switching frequency and have up to
50A of current handling capability.
Leveraging the company’s expertise in MOSFETs, gate driver ICs,
and packaging technology, Fairchild optimized Generation II XS
DrMOS devices for greater efficiency and developed new features.
These enhancements make the Generation II XS DrMOS family ideal for
applications such as blade servers, high performance gaming
motherboards, high performance notebooks, graphic cards, and high
current DC-DC point-of-load (POL) converters.
Devices in the portfolio offer a 5V and 3.3V Tristate level to
match the Intel® 4.0 DrMOS specification and are compatible with a
variety of PWM controllers on the market. The Generation II XS
DrMOS portfolio significantly reduces ringing due to PowerTrench®
MOSFET Shielded Gate technology in both the control FET and
synchronous FET. The synchronous FET also integrates a Schottky
diode which eliminates external snubber circuits, improving overall
performance and power density while reducing space and cost.
Generation II XS DrMOS devices also include a thermal warning
feature for customers to prevent over temperature conditions during
fault situations.
The Generation II XS DrMOS portfolio is able to meet different
customer and application needs.
