Fairchild Semiconductor Establishes Chicago Power Design Center for Industrial and Consumer Applications
South Portland, Maine — Fairchild Semiconductor adds to its growing number of worldwide Global Power Resource™ Design Centers with the addition of the Chicago, Illinois laboratory. This design center provides expertise in quasi-resonant designs offering less noise, lower EMI and higher efficiency than hard-switching, fixed-frequency designs in applications such as color TVs and set-top boxes. Additionally, Fairchild’s quasi-resonant designs offer design engineers the advantage of a highly integrated solution that combines a MOSFET and controller in one package. Cost-sensitive designs in industrial and consumer applications can realize a lower overall system cost through a reduction in the amount of filtering as well as heat sink size and by the reduced number of components.
