Multi-Chip Module Integrates FETs and Driver

Fairchild Semiconductor’s FDMF6700 is an optimized and integrated FET-plus-driver power stage in a 6-mm x 6-mm MLP package. A typical buck converter in the pc board of a PC may include, per phase, three n-channel MOSFETs in a DPAK package and one driver IC in SO-8 package. 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.

Fairchild offers a broad portfolio of FET-plus-driver multi-chip modules. This family includes the FDMF8700 standard DrMOS module, the FDMF8705 low-current DrMOS module and the FDMF6700 ultra-compact DrMOS module. These parts are respectively rated for 30 A, 18 A and 25 A. The FDMF6700 is available in a 40-pin (6-mm x 6-mm) MLP, and priced at $2.50 in quantities of 1000.
