ISOLATED SEMICONDUCTOR PACKAGE WITH HV ISOLATOR ON BLOCK - A simplified explanation of the abstract
This abstract first appeared for US patent application 18603047 titled 'ISOLATED SEMICONDUCTOR PACKAGE WITH HV ISOLATOR ON BLOCK
The power converter package described in the patent application includes a leadframe with first and second die pads, supports connected to first leads and second leads, and two semiconductor dies with bond pads on the respective die pads. A transformer stack with a coil and coil contacts is sandwiched between a top and bottom magnetic sheet, with a silicon block attached to the bottom magnetic sheet. Bond wires connect the bond pads to the leads and coil contacts, and the entire assembly is encapsulated in mold, leaving the bottom of the silicon block exposed.

Original Abstract Submitted
A power converter package includes a leadframe including first and second die pads, and supports connected to first leads, and second leads. A first semiconductor die including first bond pads is on the first die pad, and a second semiconductor die including second bond pads is on the second die pad. A transformer stack includes a top magnetic sheet and a bottom magnetic sheet on respective sides of a laminate substrate that includes a coil within, and coil contacts. A silicon block is attached to the bottom magnetic sheet and edges of the laminate substrate are attached to the supports. Bond wires are between the first bond pads and the second leads, the second bond pads and the second leads, and the first and second bond pads and the coil contacts. Mold encapsulates the respective semiconductor and the transformer stack. A bottom of the silicon block is exposed from the mold.
