Abstract: <P>PROBLEM TO BE SOLVED: To provide a semiconductor device for controlling a switching power supply in which a current inflow terminal for current inflow to a starting circuit and a voltage detecting terminal for detecting brownout are provided as a common terminal to enable detection of brownout without providing a dedicated input terminal for detecting brownout.  <P>SOLUTION: A terminal VH serves both as the current inflow terminal that causes current to flow into the starting circuit 110 and the voltage detecting terminal that extracts a divided voltage from a junction 116 between voltage dividing resistors R<SB>1</SB>and R<SB>2</SB>to apply the extracted voltage to a positive terminal of a brownout detecting comparator 113. The brownout detecting comparator 113 compares the divided voltage applied to the positive terminal with a reference voltage VREF1. If the reference voltage VREF1 is higher than the divided voltage at the junction 116 when the starting circuit 110 is stopped, it means a state of detection of brownout, in which logical synthesis is carried out at a logical synthesizing circuit 130 and then a logic L is output to a driver control circuit 135 after an elapse of a prescribed delay time given by a delay circuit 133.
