Fairchild Semiconductor’s Next Generation DrMOS Delivers Over 92 Percent Peak Efficiency in the Industry’s Smallest Package

Fairchild Semiconductor (NYSE: FCS) introduces XS(TM) DrMOS, the industry's first high-performance and space-efficient 6mm x 6mm DrMOS solution for synchronous DC-DC buck regulators for computing, game console and consumer Point-of-Load (POL) applications. The FDMF6704 is a FET-Plus-Driver module that replaces one driver IC, one high-side MOSFET, two low-side MOSFETS and one bootstrap Schottky diode in an ultra-compact package. The thermally enhanced 6mm x 6mm MLP package saves 84 percent board space compared to discrete solutions and 44 percent compared to 8mm x 8mm MLP packaged DrMOS modules. It delivers 92 percent peak efficiency, enabling applications to meet stringent energy-efficiency specifications such as ENERGY STAR(R), Climate Savers(R) and Green Grid(SM).

Packed with advanced features, the FDMF6704 has been designed and optimized to work with a wide variety of controllers in the market. It is compatible with both Tri-State and Non-Tri-State PWM controllers. To further ensure compatibility, the FDMF6704 has its PWM threshold levels tailored to meet a broad range of controllers available in the market. A 5V gate driver circuit and an improved PCB interface guarantee higher performance from this compact module. Fairchild's advanced SyncFET(TM) technology is integrated within the module's low-side MOSFET further ensuring higher performance. The module is also furnished with a diode emulation (SMOD) function for increased light loading efficiency.

Fairchild Semiconductor's DrMOS, the FDMFxxxx series, is a complete family of fully optimized, integrated FET-plus-Driver multi-chip power stage modules designed for multiple synchronous buck converter applications. These multi-chip modules are designed to achieve the optimal solution for a given application by using components that are matched electrically, thermally and mechanically.

The FDMF6704 utilizes lead-free (Pb-free) terminals and has been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. All of Fairchild's products are designed to meet the requirements of the European Union's Directive on the restriction of the use of certain substances (RoHS).
