るエラー検出回路。 A circuit that detects an error between a feedback voltage and a control voltage and controls the detected output to a control value, and a circuit that detects an error when the feedback voltage becomes a value lower than or higher than a certain level than the control voltage. In the error detection circuit of the equipped device, a resistor for adjusting the error detection level is provided,
An error detection circuit characterized in that the error detection level adjusting resistor changes the error detection voltage while maintaining a constant relationship as the control voltage changes.
