Abstract:
1. A DC-DC converter, comprising: a boost converter including a first switching element, a second switching element, and a first inductor; an inverting converter including a third switching element, a fourth switching element, and a second inductor; a switching controller for controlling the first, second, third, and fourth switching elements; and a current sensing unit for sensing an amount of current that flows through the first inductor and for supplying a first limit signal to the switching controller if the amount of sensed current is greater than or equal to a first reference current amount, wherein the switching controller controls the first switching element and the second switching element to reduce the amount of current that flows through the first inductor if the first limit signal is received and turns off the first switching element and the second switching element if the first limit signal is supplied more than a reference number of times within a first reference time.
