1. An integrated circuit package for use in a switch mode power converter, comprising:

  • an encapsulation;

    a lead frame, a portion of the lead frame disposed within the encapsulation, the lead frame including a first conductor having a first conductive loop disposed substantially within the encapsulation, wherein the lead frame further includes a second conductor galvanically isolated from the first conductor, wherein 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 coupled to the first conductor; and

    a second control die including a second control circuit coupled to the second conductor, wherein one or more control signals are communicated between the first and second control dice through the communication link.
