Abstract: 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.
