Abstract: A new packaging technology which improves the electrical and mechanical performance of the circuits using magnetic elements. High frequency current loops generate electromagnetic fields which are radiated or induce high frequency current in the rest of the circuit.

By separating the high frequency switching electronic components from the rest of the electronic components and locating them on the same multilayer PCB where the magnetic element is constructed, optimal results are obtained.
