Abstract
A control device for a switching regulator having two or more converter stages operating with interleaved operation, each converter stage including an inductive element and a switch element, generates command signals having a switching period for controlling switching of the switch elements, and determining alternation of a storage phase of energy in the respective inductive element and a transfer phase of the stored energy onto an output element. The control device generates the command signals phase-offset by an appropriate fraction of the switching period to obtain interleaved operation. In particular, a synchronism stage generates a synchronism signal and a control stage generates the command signals for the converter stages timed by the same synchronism signal.
