Fairchild Introduces Next Generation DrMOS; Delivers Over 92% Peak Efficiency In Small Package
Fairchild Semiconductor introduced its XS™ DrMOS, described as the industry’s first high-performance and space-efficient 6 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 a compact package.
The thermally enhanced 6 x 6mm MLP package is said to save 84% board space compared to discrete solutions and 44% compared to 8 x 8mm MLP packaged DrMOS modules. It delivers 92% peak efficiency, enabling applications to meet stringent energy-efficiency specifications such as ENERGY STAR®, Climate Savers® and Green Grid.™
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 are said to guarantee higher performance from this compact module. Fairchild’s advanced SyncFET™ technology is integrated within the module’s low-side MOSFET. 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. The company claims that 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.
The units are priced (each, 1000 pcs.) at US $1.50 with a delivery of 12 week ARO.
