Summary:In this paper different output stage topologies for DC-DC buck converters in 65 nm CMOS technology operating in Pulse Width Modulation - Discontinuous Conduction Mode for battery voltages up to 5 V are compared. The paper shows which parameters of the power transistors have to be considered for highly efficient DC-DC buck converter designs. Furthermore the different output stage topologies are compared in terms of losses. By means of the presented evaluation procedure the best output stage topology for a given technology can be found.
