  • Patent number: 10720839
    Abstract: A switching converter and a method for providing an output voltage is presented. The switching converter includes an inductor coupled to a pair of power switches, a signal generator and a controller. The first power switch is used to magnetize the inductor, while the second power switch is used to de-magnetize it. The signal generator is adapted to generate a modulated signal having a pulse width variable between a minimum value and a maximum value and to drive the first and second power switches based on the modulated signal. Upon identifying that the modulated signal has the minimum pulse width value, the controller increases a reverse current flowing from the inductor through the second power switch to prevent the output voltage from increasing above a target value.
