Zusammenfassung:	A power supply circuit may include at least a first and a second current generator. Each current generator is implemented with an electronic converter comprising a switching stage, a current sensor generating a feedback signal, and a regulator circuit configured to drive the switching stage as a function of the feedback signal. Specifically, each current sensor is a low-side current sensor configured to generate a feedback signal indicative of the current received via the negative terminal of the respective current generator. The power supply circuit may include also include a control circuit configured for various tasks pertaining to the first and second generators.
