Zusammenfassung:	A regulated charge pump includes a comparator having a first input coupled to an output of the regulated charge pump, a second input configured for receiving a reference voltage, and an output for generating an output voltage representing a difference between a charging current of the regulated charge pump and a load current of a load coupled to the output of the regulated charge pump; a first converter having an input coupled to the output of the comparator, and an output connected to a control bus configured to indicate an adjustment of the charging current in response to the comparator output; and a driving stage having a first input coupled to the control bus, and an output for providing the charging current, wherein the output of the driving stage comprises the output of the regulated charge pump.
