Sumida Group has reinvented the dc-dc power module by literally turning it inside out. The new power modules have achieved performance improvements through a new patent-pending design concept, where the magnetic material forms the entire package and all components are mounted within the inductor. The maximum volume can therefore be available for the inductor, allowing very low dc resistance and
