Abstract

An embodiment circuit comprises first and second output nodes with an inductor arranged therebetween, and first and second switches coupled to opposed ends of the inductor. The switches are switchable between non-conductive and conductive states to control current flow through the inductor and produce first and second output voltages. The current intensity through the inductor is compared with at least one reference value. Switching control circuitry is coupled with the first and second switches, the first and second output nodes, and current sensing circuitry, which is configured to control the switching frequency of the first and second switches as a function of the output voltages and a comparison at the current sensing circuitry. The switching control circuitry is configured to apply FLL-FFWD processing to produce the reference values as a function of a timing signal, targeting maintaining a constant target value for the converter switching frequency.
