The invention relates to a circuit configuration for operating at least one discharge lamp, and to a method for generating an auxiliary voltage, wherein the device for generating the auxiliary voltage (Vcc) further comprises a transformer (TR) having a primary winding (PW) and a secondary winding (SW), said transformer (TR) being coupled to the first and the second input connection, the connection for provision of the auxiliary voltage (Vcc) and the switch (Qiss) such that a current through the switch (Qiss) leads to a current through the primary winding (PW), leading to a current through the secondary winding (SW) and thus to a charging the first capacitor (Cvcc). The invention further relates to a method for generating an auxiliary voltage in the corresponding circuit configuration.
