  • Publication number: 20230387817
    Abstract: A voltage converter includes a switch network, a rectifier, and a transformer coupled between the switch network and the rectifier. The voltage converter includes an adaptive ON-time generation circuit having a control input and a control output, the control input. The adaptive ON-time generation circuit is configured to receive a WAKE signal to turn ON the switch network, generate a signal indicative of an OFF time of the switch network, and determine an ON time for the switch network based on the signal indicative of the OFF time.

  • Publication number: 20230005652
    Abstract: An apparatus has a laminate substrate that has a first surface and an opposite second surface. A laminate transformer is located within the laminate substrate between the first surface and the second surface. The transformer has a first coil adjacent the first surface and a second coil adjacent the second surface. A magnetic core element on the first surface overlaps a portion of the first coil. A lead frame on the first surface is spaced apart from the magnetic core element. A portion of the lead frame overlaps a portion of the first coil to provide a thermal conductive path.

  • Publication number: 20220310302
    Abstract: A microelectronic device includes a magnetic component having a first magnetic core segment and a second magnetic core segment, with a winding lamina between them. The first magnetic core segment includes a winding support portion with ferromagnetic material. The winding lamina is attached to the winding support portion. The first magnetic core segment also includes an extension portion with ferromagnetic material extending from the winding support portion. The winding lamina has winding loops of electrically conductive material that surround ferromagnetic material. A filler material is formed between the winding lamina and the first magnetic core segment, contacting both the winding lamina and the first magnetic core segment. The second magnetic core segment is attached to the extension portion of the first magnetic core segment. The second magnetic core segment includes ferromagnetic material. The winding loops are electrically coupled to external leads through electrical connections.

  • Patent number: 11270937
    Abstract: An integrated circuit (IC) package comprises a semiconductor die, a leadframe comprising a plurality of leads coupled to bond pads on the semiconductor die, and an electrically conductive member electrically coupled to the leadframe. A magnetic mold compound encapsulates the electrically conductive member to form an inductor. A non-magnetic mold compound encapsulates the semiconductor die, the leadframe, and the magnetic mold compound.

  • Publication number: 20210375540
    Abstract: A laminate embedded core and coil structure comprises a magnetic core embedded in a laminate structure that includes two types of laminates. A first laminate embeds the coils of the structure and a second laminate fills space between the magnetic core and the first laminate, as well as space below the magnetic core and lower surface of the first laminate. The first and second laminates form a laminate structure that protects and improves isolation of the magnetic components. Solder resist encloses the laminate structure, magnetic core and coils. The laminate embedded core and coil structure may be assembled on a transformer leadframe of various types using non-conductive paste.

  • Patent number: 10109404
    Abstract: A low profile inductor structure suitable for use in a high power density power converter has one or more windings formed by vias through a thin, generally planar body of magnetic material forming the inductor core and conductive cladding on the body of magnetic material or material covering the magnetic material body. Variation of inductance with load current and other operational or environmental parameters is reduced to any desired degree by forming a slot that removes all or a portion of the magnetic material between the locations of the vias.
