Claim 16:
17. An isolated DC-DC 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 comprising a gate driver including first bond pads on the first die pad and a second semiconductor die comprising a power field effect transistor (FET) module comprising at least one power FET including second bond pads on the second die pad;
the molded transformer comprising a top side magnetic sheet and a bottom side magnetic sheet each comprising a magnetic mold material comprising magnetic particles and a second dielectric material encapsulating the magnetic particles on respective sides of a laminate substrate comprising a first coil and a second coil and a dielectric material, including coil contacts on a top surface of the laminate substrate;
wherein edges of the laminate substrate are attached to the supports;
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, for the second semiconductor die, and for the molded transformer.
