Abstract: 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.
