Classification: CPC H | IPC H

Claim 10:
11. An isolated power converter package, comprising:
a leadframe including a first die pad and a second die pad, supports for supporting a transformer stack connected to a first plurality of leads, and 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 transformer stack comprising a top side magnetic sheet and a bottom side magnetic sheet on respective sides of a laminate substrate comprising a coil within a dielectric material, including coil contacts on a top surface of the laminate substrate;
a silicon block attached to the bottom side magnetic sheet;
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, the second semiconductor die, and the transformer stack,
wherein a bottom side of the silicon block is exposed from the mold compound at a bottom side of the isolated power converter package,
wherein the isolated power converter package comprises an isolated DC/DC converter, wherein the first semiconductor die comprises a gate driver, and wherein the second semiconductor die comprises a power field effect transistor (FET) module comprising at least one power FET.
