Inhalt:
By using an integrated, galvanically isolated, separated buck/boost topology (short iisb2 topology) a high efficiency 48 V to 1 V Point of Load (PoL) unit is demonstrated. This paper describes why the proposed topology can be even useful in typical non-insulated DC/DC applications, like processor supplies by deducing the proposed topology from the well-known single stage hard-switched half-bridge with current doubler rectifier topology. Moreover, it will be shown why the special requirements for processor PoL applications can be easier fulfilled by the proposed topology.
