Claim 0:
1. A booster circuit comprises:
a boost converter configured to boost an input voltage and perform feedback control such that an output voltage becomes a set value on the basis of a first voltage applied to a feedback terminal and an internal feedback reference voltage; and
a control circuit comprising:
a power supply unit configured to generate a reference voltage with a smaller error than the feedback reference voltage; and
a control unit comprising:
a second voltage dividing unit configured to generate a second voltage corresponding to the output voltage by dividing the output voltage by resistance; and
a comparator configured to compare the second voltage generated by the second voltage dividing unit with the reference voltage, and configured to output a voltage indicating a comparison result,

wherein the boost converter comprises:
a first voltage dividing unit configured to divide the output voltage by resistance and output the first voltage according to the voltage indicating the comparison result of the comparator to the feedback terminal.
