Abstract
An error signal generating unit is configured such that (i) in a calibration period, the error signal generating unit is set to a first state in which it amplifies an error signal by amplifying a difference between a predetermined first reference voltage and the lowest one from among multiple first detection voltages, and such that (ii) after the calibration period, the error signal generating unit is set to a second state in which it generates the error signal by amplifying a difference between a second detection voltage and a second reference voltage. A reference voltage setting unit holds, as the second reference voltage, the largest value of the second detection voltage detected in the calibration period.
