Power supply circuit arrangement for electronic load circuit

A circuit configuration for supplying an electronic load circuit with an electrical high voltage, whose value has a magnitude greater than a value of a voltage supply that supplies the circuit configuration. The circuit configuration has a pump circuit that is electrically connected to the load circuit and outputs the high voltage to the load circuit on the basis of an internal switching signal which has a predetermined pump frequency. The electrical pump power, which is taken up by the load circuit, of the pump circuit essentially depends both on the value of the supply voltage and on the value of the pump frequency of the switching signal of the pump circuit. The circuit configuration has an electronic control circuit that is assigned to the pump circuit and supplied with a voltage derived at least from the supply voltage of the pump circuit. In dependence on a control signal that depends on the value of the supply voltage, the control circuit emits to the pump circuit a switching signal that acts on the pump frequency for generating the high voltage which is output by the pump circuit in such a way that the value of the pump frequency of the switching signal is inversely proportional to the value of the supply voltage.
