Abstract: Initial calibration is performed only under normal-temperature environment, and accurate current control is performed under practical use temperature environment. A temperature sensor 171 is arranged close to a current detection resistor 126 having predetermined temperature characteristics. Resistance values are estimated in a calibration environment and a practical use environment, an actually measured load current in the calibration environment corresponding to a target load current is stored as control characteristic data, a corrected target current corresponding to the target load current is calculated, and a converted target current based on a change ratio of current detection resistance is controlled as a target current for current control. A resistance change amount by heat generation of the current detection resistor 126 which cannot be entirely detected by the temperature sensor 171 is corrected in control characteristic data, such that linearity of control characteristics is improved.
