Abstract: An integrated circuit (100) and method of making an integrated circuit (100) is provided. The integrated circuit (100) includes a substrate (102) having an electronic component (104). A substrate-based coil (110, 112) is on the substrate (102) and the substrate-based coil (110, 112) is electrically coupled to the electronic component (104). A magnetic mold compound (134) encapsulates the substrate-based coil (110, 112) and the electronic component (104).

Abstract: In examples, a method (100) of manufacturing a transformer device comprises providing a first magnetic member (102) and providing a laminate member containing primary and secondary transformer windings wound around an orifice extending through the laminate member (106). The method further comprises positioning a build up film abutting the laminate member (104). The method also comprises positioning at least a portion of a second magnetic member in the orifice (110). The method further comprises heat pressing at least one of the first and second magnetic members such that a distance between the first and second magnetic members decreases and such that the build-up film melts, thereby producing a transformer device (112, 114).

Abstract: A method (100) includes performing a printing process that deposits (106) a magnetic paste onto a first side and into an opening of a laminate; curing (108) the magnetic paste to form a first transformer core piece having a first portion along the first side and a second portion filling the opening of the laminate; joining (118, 120, 122) a second transformer core piece to a side of the second portion of the first transformer core piece to form a transformer. A transformer includes a laminate; a first core piece; and a second core piece, the first core piece comprising: a cured magnetic paste, a first portion along a side of the laminate, and a second portion filling an opening of the laminate, the second core piece extending along a side of the second portion of the first transformer core piece, and the laminate having windings that encircle the opening.
