出力電圧安定化回路。[Claims for Utility Model Registration] In a DC-DC converter output voltage stabilization circuit that stabilizes the output voltage by controlling the input voltage of the DC-DC converter to a predetermined value, the output voltage of the DC-DC converter is detected. An output voltage detection means compares the output voltage detected by the output voltage detection means with a reference voltage, and outputs a predetermined voltage Vmin when the output voltage is higher than the reference voltage, and outputs a predetermined voltage Vmin when the output voltage is higher than the reference voltage. If it is lower than the reference voltage, the voltage V
1. A DC-DC converter output voltage stabilizing circuit comprising: input reference voltage setting means for outputting a predetermined voltage Vmax higher than min and supplying it as a reference voltage for controlling the input voltage.
