Abstract
A circuit configuration for providing a voltage supply for a driver circuit driven by a controller, contains a controller for driving a driver circuit, and an intermediate circuit for providing a DC voltage. The intermediate circuit is connectable to a voltage source. A first voltage regulating circuit is provided for generating an auxiliary voltage from the DC voltage. A second voltage regulating circuit is provided for generating a first supply voltage for the controller from the auxiliary voltage. A third voltage regulating circuit is provided for generating a second supply voltage for the driver circuit from the auxiliary voltage. In this case, the third voltage regulating circuit generates the second supply voltage in a manner dependent on a control signal from the controller.
