Abstract: An electronic device is provided. The electronic device includes: a first transistor configured to connect an input voltage node to a switching node; a second transistor configured to connect the switching node to a ground node; a latch circuit configured to generate a first signal having a first frequency and to control the first frequency based on a level of a load current; a switching modulation circuit configured to generate a second signal having a second frequency which is 1/N (where N is a natural number) times the first frequency; and a controller configured to control each of the first transistor and the second transistor, based on the second signal.
