Abstract
A method for DC/DC conversion comprises operating in a Boost mode of operation or in a Buck-Boost mode of operation. Furthermore, the method comprises switching from the Boost mode of operation to the Buck-Boost mode of operation, if a desired value (VOUTR) of an output voltage (VOUT) which is generated from a supply voltage (VIN) by the DC/DC conversion is smaller than a first reference voltage (VR1). The method also comprises switching from the Buck-Boost mode of operation to the Boost mode of operation, if the desired value (VOUTR) is larger than a second reference voltage (VR2).
