Abstract
A power source control circuit is a hysteresis control circuit controlled by current mode. The power source control circuit includes a DC input power source, an input capacitor, a first switching element, a second switching element, an inductor, a current detector, a diode, a third switching element, a hysteresis current controller, and a load. The first end of the inductor is coupled to the second terminal of the first switching element and the first terminal of the second switching element. The second end of the inductor is coupled to the first terminal of the third switching element. The inductor outputs a pulse width modulated output current that is in the PWM mode and that flows into the load.
