Fairchild Introduces DrMOS FET Plus Driver Multi-Chip Module for Synchronous Buck Converters

July 11, 2007 by Jeff Shepard

Fairchild Semiconductor announced the FDMF6700, a fully optimized and integrated FET plus driver power stage solution in an ultra-compact 6mm x 6mm MLP package. The FDMF6700 is claimed to offer designers a solution for severely space-constrained applications such as small-form-factor desktops, media center PCs, ultra-dense servers, blade servers, advanced gaming systems, graphic cards, networking and telecom equipment, and other dc-dc applications with limited board space.

According to the company, a typical buck converter in a PC motherboard may include, per phase: three N-channel MOSFETs in a DPAK package and one driver IC in SO8 package. By replacing these components with the new highly integrated FDMF6700, designers save more than 80% of valuable board space. In addition, through the integration of components into an optimized single-package solution, parasitic inductances of board traces and leads of the individual discrete packages are eliminated, improving overall efficiency.

"Our FDMF6700 in the 6mm x 6mm MLP package is 44% smaller than any other DrMOS device available in the market today," stated Roberto Guerrero, World Wide Segment Manager for Desktop, Server and Gaming Products in Fairchild’s Functional Power Group. "This new solution places Fairchild as the leader in ultra-high-density DrMOS technology."

The FDMF6700 is available in a 40-pin (6mm x 6mm) MLP. These products utilize lead-free (Pb-free) terminals and have been characterized for moisture sensitivity in accordance with the Pb-free reflow requirements of the joint IPC/JEDEC standard J-STD-020. The product is designed to meet the requirements of the European Union Directive on the restriction of the use of (certain) hazardous substances (RoHS).

Priced (each, 1000 pcs) at US$ 2.50, the FDMF6700 is available now with a delivery time of 8 weeks ARO.
