電源制御回路。A switching means for opening and closing the DC input power supply, so as to maintain the desired DC output voltage at a predetermined voltage through the switching means,
In a power supply circuit comprising a first control means for controlling opening and closing of the opening/closing means, an output current detection means for detecting an output current supplied to the outside via the output voltage, and a detection of the output current detection means. a second control means that compares the voltage with a predetermined reference voltage and controls opening and closing of the opening/closing means in priority over the first control means so that the output current does not exceed a predetermined current value corresponding to the reference voltage; control means for switching the reference voltage so that the divided voltage value of the output voltage becomes the reference voltage after the output voltage falls below a predetermined lower limit value; 1. A power supply control circuit comprising variable setting means for variably setting a voltage and a lower limit value at the same time.
