Abstract
A circuit arrangement for generating at least two interdependent supply voltages from an input voltage includes a first control stage for controlling the actual value of a first one (Ua1) of the supply voltages to a first nominal value which is adjustable between a first upper and a first lower tolerance limit. At least one further control stage controls the actual value of each further one of the supply voltages (Ua2, . . . , Uan) to a further nominal value, which is preferably adjustable within a range between each time a further upper and a further lower tolerance limit, by varying the first nominal value in the range between the first upper and the first lower tolerance limit in response to control signals obtained by a comparison performed between the actual values of the further supply voltages (Ua2, . . . , Uan) and the associated further nominal values in the associated control stages. This simplified circuit arrangement improves the accuracy of the supply voltages under load conditions.
