A circuit arrangement for determining a target value of a current limit of a current regulator, the circuit arrangement comprising: - an energy storage, which outputs an output voltage (Uo); - a comparator device for comparing a value of an electrical input voltage (Uacc) with a first upper threshold value, with a second upper threshold value, with a first lower threshold value and with a second lower threshold value; - a first increasing device; - a second increasing device; - a first reducing device; - a second reducing device; - wherein, if the input voltage (Uacc) is greater than the first upper threshold value, the target value is increased and the first increasing device is switched on, thus increasing the output voltage by a first value; - wherein, if the input voltage (Uacc) is greater than the second upper threshold value, the target value is increased and the second increasing device is switched on, thus increasing the output voltage by a second value; - wherein, if the input voltage (Uacc) is smaller than the first lower threshold value, the target value is reduced and the first reducing device is switched on, thus reducing the output voltage by a third value; - wherein, if the input voltage (Uacc) is smaller than the second lower threshold value, the target value is reduced and the second reducing device is switched on, thus reducing the output voltage by a fourth value; - wherein a first time constant is assigned to the first upper threshold value, and a second time constant is assigned to the second upper threshold value, wherein the first time constant is greater than the second time constant, so that when the second upper threshold value is exceeded, the target value of the current limit is changed more quickly than when the first upper threshold value is exceeded; - wherein a third time constant is assigned to the first lower threshold value, and a fourth time constant is assigned to the second lower threshold value, wherein the third time constant is greater than the fourth time constant, so that when the second lower threshold value is exceeded, the target value of the current limitation is changed more quickly than when the first lower threshold value is exceeded. - an energy storage, which outputs an output voltage (Uo); - a comparator device for comparing a value of an electrical input voltage (Uacc) with a first upper threshold value, with a second upper threshold value, with a first lower threshold value and with a second lower threshold value; - a first increasing device; - a second increasing device; - a first reducing device; - a second reducing device; - wherein, if the input voltage (Uacc) is greater than the first upper threshold value, the target value is increased and the first increasing device is switched on, thus increasing the output voltage by a first value; - wherein, if the input voltage (Uacc) is greater than the second upper threshold value, the target value is increased and the second increasing device is switched on, thus increasing the output voltage by a second value; - wherein, if the input voltage (Uacc) is smaller than the first lower threshold value, the target value is reduced and the first reducing device is switched on, thus reducing the output voltage by a third value; - wherein, if the input voltage (Uacc) is smaller than the second lower threshold value, the target value is reduced and the second reducing device is switched on, thus reducing the output voltage by a fourth value; - wherein a first time constant is assigned to the first upper threshold value, and a second time constant is assigned to the second upper threshold value, wherein the first time constant is greater than the second time constant, so that when the second upper threshold value is exceeded, the target value of the current limit is changed more quickly than when the first upper threshold value is exceeded; - wherein a third time constant is assigned to the first lower threshold value, and a fourth time constant is assigned to the second lower threshold value, wherein the third time constant is greater than the fourth time constant, so that when the second lower threshold value is exceeded, the target value of the current limitation is changed more quickly than when the first lower threshold value is exceeded.
