Abstract
In a current mode DC-DC converter, the current flowing through a coil is switched and an output characteristic is controlled. The output of the converter is detected and the current flowing through the coil is limited according to the detected output only when the detected output is larger than a predetermined value to reduce the start-up time and improve output voltage regulation.
