<p><P>PROBLEM TO BE SOLVED: To provide a technique for properly supplying power while selectively using generating methods of a plurality of types of analog control signals in power supply control. <P>SOLUTION: A method of manufacturing a power supply control device for controlling a power circuit for supplying power of L channels is provided. The manufacturing method includes: a preparing step of preparing a control circuit for output of a plurality of types of control signals including a digital control signal and a pulse width modulation signal, a digital-to-analog converter having M channels, N demodulation circuits each of which generates an analog control signal by demodulating the pulse width modulation signal; a first connecting step of electrically connecting M channels of the digital-to-analog converter to be connected to the power circuit to the control circuit; and a second connecting step of electrically connecting N demodulation circuits to be connected to the power circuit to the control circuit. N is a positive integer of M or smaller. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
