  • VOLTAGE CONVERTER AND POWER MANAGEMENT DEVICE INCLUDING THE SAME
    Publication number: 20240162802
    Abstract: A voltage converter includes a converting circuit having an inductor connected to a switching node, a first switch element connected between the switching node and a ground voltage, and a second switch element connected between the switching node and an output node; and a switching control circuit configured to adjust a feedback voltage divided from an output voltage of the output node based on a current state of the inductor, and configured to generate switching control signals for charging the inductor with an input voltage and discharging a voltage charged in the inductor, based on a sensing signal based on a current of the inductor and the adjusted feedback voltage.
