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. To reduce the radiated field, these loops have been minimized by locating the high frequency switching components close to each other and very close to the magnetic elements. 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.
