Original Abstract Submitted
provided is a hybrid buck converter including a first pmos transistor and a second pmos transistor electrically connecting a power supply voltage node with a first switching node, a first nmos transistor and a second nmos transistor electrically connecting a ground node with the first switching node, an inductor electrically connecting the first switching node with a second switching node, a third nmos transistor electrically connecting the second switching node with a first output node, a third pmos transistor electrically connecting the second switching node with a second output node, a shunt regulator that is driven based on a second output voltage of the second output node, a first pwm controller adjusting, based on a pulse width control of first pmos transistor and first nmos transistor, a magnitude of an inductor current, and a second pwm controller adjusting, based on a pulse width control of first pmos transistor and first nmos transistor, a magnitude of the second output voltage.
