Abstract :
The tendency to push down supply voltages (3.3 V, 2.7 V...) in telecommunication equipment makes DC/DC conversion systems be placed as close as possible to the load, thus minimizing losses due to high currents. Size is a critical feature in these supply systems, with passive components usually being the bulkiest elements. A 10 watt DC/DC converter is presented in this paper where passive components have been integrated using hybrid technology, thus allowing to obtain high power density of 6.25 W/cm3
