Abstract

Aspects of the present disclosure include systems, structures, circuits, and methods providing voltage-isolated integrated circuit (IC) packages or modules having a transformer integrated with or implemented on a lead frame. A portion of transformer windings may include a conductive portion of a lead frame. Conductive structure, such as wire bonds, may be used for other portions of transformer windings. In some examples, an insulating coating may be placed on the package to increase the isolation capability of the final package. The IC packages and modules may include various types of circuits; in some examples, IC packages or modules may include a galvanically isolated gate driver or other high voltage circuit.
