Critical Embedded Power

Fairchild offers a full line of solutions for telecommunication industrial applications. The products cover off-line and isolated power converters to non-isolated power converters. The off-line and isolated solutions include flyback converters, LLC converters, and SR Controllers. The non-isolated DC-DC solutions cover step-up and step-down converters with and without integrated switches for all the internal chipsets' needs.
