Abstract: An inductor-less power converter for converting an input voltage at an input terminal to an output voltage at an output terminal is provided, with a conversion ratio between the input and output voltage. The converter can be an inductor-less power converter which is configured for Direct Current, DC, to DC, DC-DC conversion of an input voltage to an output voltage. The input voltage is provided at an input terminal pair whereas the output voltage is provided at an output terminal pair. The ratio between the input voltage and the output voltage defines the conversion ratio, which may be either larger than one or smaller than one, meaning that the voltage may be stepped-up or stepped-down and thus increased or lowered.
