A control device of a plurality of switching converters, each converter having at least one power switch and being associated with a control circuit of said at least one power switch, the control device comprising a comparator circuit that compares a signal representative of the load of the plurality of converters with a plurality of reference signals and suitable to enable or disable at least one of said plurality of control circuits in response to said comparison.
A circuit for controlling a plurality of switching converters having at least one power switch and associated with a control circuit, the circuit comprising:
- a comparator circuit coupled to each control circuit and receiving a plurality of reference signals and a control signal representative of the load of the plurality of converters and outputting an enable/disable signal to each of the plurality of circuits in response to the comparison of the plurality of reference signals with the control signal.
