Abstract

According to an aspect of the present invention, there is provided a DC-DC converter including a high-side transistor, a low-side transistor, a first current detector, a second current detector and a driver. The first current detector monitors a first current flowing through the high-side transistor and outputs a first control signal when the first current becomes smaller than a first reference value. The second current detector monitors a second current flowing through the low-side transistor and outputs a second control signal when the second current becomes smaller than a second reference value. The driver turns on the low-side transistor based on the first control signal and turns on the high-side transistor based on the second control signal.
