Abstract
Official abstract text for this publication.
An integrated circuit package for use in a switch mode power converter comprises an encapsulation and a lead frame. A portion of the lead frame is disposed within the encapsulation. The lead frame includes a first conductor having a first conductive loop disposed substantially within the encapsulation. The lead frame also includes a second conductor galvanically isolated from the first conductor. The second conductor includes a second conductive loop disposed substantially within the encapsulation proximate to and magnetically coupled to the first conductive loop to provide a communication link between the first and second conductors. A first control die including a first control circuit is coupled to the first conductor. A second control die including a second control circuit is coupled to the second conductor. One or more control signals are communicated between the first and second control dice through the communication link.
