  • Driving circuit and control method thereof
    Patent number: 9585204
    Abstract: A driving circuit includes: a switching element having a first terminal to receive an input voltage, and a second terminal; an inductor coupled to the second terminal of the switching element; a switch and a current sensing element coupled in series to the second terminal of the switching element; and a control module compensating a voltage sensed by the current sensing element based on at least one of the input voltage and an output voltage across the switching element and the inductor to generate a compensated signal, and switching the switch from an ON state to an OFF state when the compensated signal exceeds a reference threshold for a delay time.
