Abstract
The present document describes a control circuit for controlling a buck-boost power converter, which is configured to provide at an output node of the power converter an output current at an output voltage based on electrical power at an input voltage which is provided at an input node of the power converter. The control circuit is configured to determine an operation mode that the power converter is operated in; to determine an error voltage signal based on the output voltage, based on a reference voltage for the output voltage and based on the determined operation mode of the power converter; and to determine a control signal for controlling one or more power switches of the power converter in dependence of the error voltage signal.
