The circuit comprises a plurality of supply modules for delivering current to a common load. Each supply module (3) is equipped with a driving circuit (23, 25, 27) for controlling the current delivered by the module. The supply modules are connected together by a share bus (9) on which a signal is present for balancing the current delivered by each supply module, in such a way as to control and reduce the difference between the current delivered by a dominant supply module and the current delivered by the remaining supply modules of the circuit. Associated to each supply module are means (31) for generating a PWM signal, the duration of which is proportional to the current delivered by the respective supply module. In addition, each supply module is connected to the share bus in such a way that on the latter there is present a digital share signal, which is a function of the digital PWM signal generated by the dominant supply module. In each supply module, means are provided for generating an error signal, the said means generating, on the basis of the PWM signal of the module itself and on the basis of the digital share signal, an error signal, which constitutes a feedback signal for the driving circuit of the supply module.
