Abstract

PURPOSE:To vary a constant voltage continuously by the digital control, by providing an input part for a digital signal in a feedback control circuit and by inputting the digital signal for setting an output voltage to this part from the external. CONSTITUTION:A switching regulator (a) is inserted between the DC power supply circuit of the input side and the output side, and a feedback controlling circuit 9 is provided with an input part which receives setting of an output voltage by a digital signal, and the output voltage of the switching regulator (a) is set from the external by the digital signal. Consequently, the DC power source regulated to a constant voltage has the voltage varied continuously by the digital control.
