Abstract
A power source circuit includes an inductor, a reservoir capacitor, and a switching control part that generates ON/OFF control signals to each of first and second switches. The first switch is connected between a first power voltage terminal and a first node to form a first current path between the first power voltage terminal and the first node in response to a driving signal of the switching control part. The second switch is connected between the first node and a second power voltage terminal to form a second current path between the first node and the second power voltage terminal in response to the driving signal. The inductor is connected to the first node to provide an average voltage between the first power voltage terminal and the second power voltage terminal. The capacitor is connected in parallel with the inductor to store the average voltage.
