Abstract
A system for converting a DC input voltage to a DC output voltage includes at least one integrated circuit die electrically coupled to a leadframe. An inductor is also coupled to the leadframe and electrically coupled to the integrated circuit die. An inductor casing generally surrounds the inductor, and a molding encapsulates the integrated circuit die, a portion of the leadframe, and a portion of the inductor. The integrated circuit die and the inductor are operable to receive the direct current input voltage and to convert the direct current input voltage to the direct current output voltage.
