Assignee: TEXAS INSTRUMENTS INCORPORATED
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. An isolated converter package, comprising:
a 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;
a silicon block attached to the bottom side magnetic sheet;
a first die pad and a second die pad and supports for supporting the transformer stack;
a first plurality of leads connected to the supports and a second plurality of leads;
a first semiconductor die on the first die pad, a second semiconductor die on the second die pad, and the transformer stack with edges of the laminate substrate on the supports and the silicon block below the supports;
wirebonds between bond pads on the first semiconductor die and the second plurality of leads, between bond pads on the second semiconductor die and the second plurality of leads, between first bond pads on the first semiconductor die and contacts on the laminate substrate and between bond pads on the second semiconductor die and contacts on the laminate substrate; and
a mold compound providing encapsulation for the first semiconductor die, the second semiconductor die, and for 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 package.
