Abstract:
A semiconductor device for power supply control generating and outputting a driving pulse for performing control to turn on/off a switching element by inputting voltage in proportion to current in the primary-side winding wire and an output voltage detection signal from a secondary side, the device including: a high-voltage input start terminal to which alternating-current voltage of AC input or rectified voltage is input; voltage comparison circuits to which voltage obtained by dividing voltage input to the high-voltage input start terminal is input and which compare the input voltage with any of reference voltages; a timer circuit which starts to measure a predetermined time at a timing of rising and/or falling of output of the voltage comparison circuits; and a discharging unit between the high-voltage input start terminal and a ground point, wherein the discharging unit is made conductive when the predetermined time is measured.

Claim (Index 3):
The semiconductor device for power supply control according to  claim 2 , comprising:\n an internal power supply circuit which is connected to the first power supply line; a third switching unit which is provided between the Zener diode and the second power supply terminal; and a fourth switching unit for supplying an internal voltage generated by the internal power supply circuit to the second power supply line, wherein the third switching unit is turned off and the fourth switching unit is turned on when the detection circuit detects that the voltage of the command input terminal is lower than the predetermined voltage value, and the third switching unit is turned on and the fourth witching unit is turned off when the detection circuit detects that the voltage of the command input terminal is higher than the predetermined voltage value.
