Abstract: A DC-DC switching converter includes an electrical network with an inductor, switches and first and second capacitors subject to first and second voltages. A control module generates first and second control signals to control the switches with a sequence of switching periods implementing, for each switching period, a phase succession including: an inductor charge phase having a first duration as a function of the first control signal; a first inductor discharge phase towards the first capacitor having a second duration as a function of the second control signal; and a second inductor discharge phase towards the second capacitor. The control module couples to the electrical network to form a signal vector including signals indicative of the first and second voltages and the current. A gain stage generates the first and second control signals by multiplying the signal vector by a gain matrix for the control module forming a linear-quadratic regulator.
