標値制御部とを備えた、 ことを特徴とするＤＣフアンモータ駆動回路。[Claims for Utility Model Registration] A drive power source for driving a DC fan motor is generated by switching a DC power supply voltage, and the voltage component of the drive power source and the load current component of the DC fan motor are each compared with a control target value, and the mutual difference between them is determined. In a DC fan motor drive circuit that feedback-controls the voltage of the drive power source and the load current of the DC fan motor by controlling the switching period with a control amount based on each deviation of the DC motor and the fan, an operation specifying means for specifying a combination of operating conditions; and storing the control target value for the voltage of the drive power source and the control target value for the load current corresponding to the specification of the operation specifying means, and and a target value control section that outputs each control target value corresponding to the above for the comparison.
