ABSTRACT:
The objective of this invention is to provide a DC-DC converter characterized by the fact that by correcting the loop gain corresponding to the switching of the operating mode, the variation in the output voltage that accompanies the switching of the operating mode can be minimized. Loop gain correction section50for correcting the gain of the feedback loop that controls output voltage VOUTis used, so that when the operating mode is switched in response to change in the input voltage VIN, the gain of the feedback loop is reduced by means of loop gain correction section50. As a result, the duty ratio of pulse-width modulation signal VPWM1output from pulse-width modulation portion20is decreased, and output voltage VOUTis controlled to be reduced. Consequently, the transient rise of output voltage VOUTthat accompanies the switching of the operating mode can be avoided, the stability of the output voltage can be improved, and the influence on the load circuit can be prevented.
