Claim 0:
1. An isolated power converter package, comprising:
a leadframe including a first die pad and a second die pad, first and second supports for supporting a molded transformer connected to a first plurality of leads, a second plurality of leads;
a first semiconductor die including first bond pads on the first die pad and a second semiconductor die including second bond pads on the second die pad;
the molded transformer attached to the first and the second supports by a die attach material, the molded transformer comprising a top side magnetic sheet and a bottom side magnetic sheet on respective sides of a laminate substrate, the laminate substrate comprising at least a first coil and a second coil and a dielectric material, including coil contacts on a top surface of the laminate substrate, wherein the top side and the bottom side magnetic sheet each comprise a magnetic mold material comprising magnetic particles and a second dielectric material;
bond wires between the first bond pads and the second plurality of leads, between the second bond pads and the second plurality of leads, between the first bond pads and the coil contacts, and between the second bond pads and the coil contacts, and
a mold compound providing encapsulation for the first semiconductor die, the second semiconductor die, and the molded transformer.
