Abstract
A DC voltage converter having a plurality of outputs and a method for converting a DC voltage into a plurality of output-side DC voltages is disclosed. A control unit is used to drive a first and a second switch to drive an energy store in such a manner that a plurality of different output voltages are provided. The switches include field effect transistors, and at least the substrate terminal of one of these field effect transistors is connected to the control unit in order to be driven using a substrate potential in a manner dependent on an operating mode of the DC voltage converter. This makes it possible to provide different voltages both in an intermittent and in a continuous operating mode of the converter with, at the same time, a high degree of efficiency.
