摘要： An operating method of a voltage converter, includes converting an input voltage to an output voltage and providing a load current corresponding to the output voltage in a pulse frequency modulation mode or a pulse width modulation mode, entering the pulse frequency modulation mode in response to an amount of the load current being less than or equal to a first threshold value, and entering the pulse width modulation mode in response to the amount of the load current being greater than a second threshold value.

摘要： 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.
