PROBLEM TO BE SOLVED: To secure a disposition space for other components around a load component and reduce radiation noise caused by a current fluctuation of high frequency from a DC converter.SOLUTION: The converter mounting substrate includes: a high frequency DC converter for providing a load component with a DC current with rapid current fluctuation; and a low frequency DC converter for providing the load component with a DC current with a current fluctuation relatively slower than that of the high frequency DC converter. The low frequency DC converter is disposed separately from the load component farther than the high frequency DC converter.SELECTED DRAWING: Figure 1 |
