Abstract

See full text

In a mode comparator of the DC-DC converter, a threshold input to the mode comparator is switched to a first threshold, if a mode signal prescribes an active mode, on the other hand, the threshold input to the mode comparator is switched to a second threshold, which is higher than the first threshold, if the mode signal prescribes an inactive mode. A lower limit value to a lower limit value setting circuit of the DC-DC converter is switched to a first lower limit value, if the mode signal prescribes the active mode, on the other hand, the lower limit is switched to a second lower limit value, which is higher than the first lower limit value, if the mode signal prescribes an inactive mode.
