MCM-L integrated transformers for low power applications

Abstract

Designs for planar magnetic core structures fabricated in printed circuit board (PCB) technology have been developed by the authors. The technology is applied to producing integrated transformers for low power conversion in this paper. It involves using processes and materials which are compatible with existing PCB techniques, and structures are designed to be integrated with other circuitry in a typical PCB layer count. Structures are designed to support voltage levels of up to 18 V at 3 W power.
