Abstract
A control device for a switching power converter having an inductor element, a switch coupled to the inductor element, a storage element coupled to an output on which an output voltage is provided, and a diode element coupled to the storage element. The control device generates a command signal to control the switch and determine storage of energy in the inductor element in a first interval, and transfer of energy onto the storage element through the diode element in a second interval. A voltage shifter module generates a feedback voltage shifted relative to the output voltage. An amplification module has a first input receiving the feedback voltage, a second input receiving the reference voltage, and an output that supplies, as a function of the difference between the feedback and reference voltages, a control signal. A control unit receives the control signal and generates the command signal to control the switch.
