Abstract
The DC-DC converter includes a mask controlling circuit that outputs an overcurrent detection mask signal that prescribes a mask period in which the overcurrent detection result signal is masked. The DC-DC converter includes a mask adjusting circuit that adjusts a length of the mask period according to the power supply voltage. The DC-DC converter includes an operation circuit that performs an operation of the overcurrent detection result signal and the overcurrent detection mask signal and outputs an overcurrent controlling signal with the overcurrent detection result signal being masked in the mask period.
