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 2):
The semiconductor device for power supply control according to  claim 1 , comprising:\n a high-voltage switching element which is connected to the high-voltage input start terminal; a first power supply terminal to which voltage induced by an auxiliary winding wire of the transformer is input; a second power supply terminal to which a receiving element that receives a command signal from outside is connected; a command input terminal to which a current-voltage converting unit that is connected in series with the receiving element and converts current flowing in the receiving element into voltage is connected; a first power supply line and a first switching unit which is provided on the first power supply line, the first power supply line being connected between the high-voltage input start terminal and the first power supply terminal via the high-voltage switching element; a second power supply line and a second switching unit which is provided on the second power supply line, the second power supply line being connected between the high-voltage input start terminal and the second power supply terminal via the high-voltage switching element; a Zener diode which is connected between the second power supply line and the ground point; a bias circuit which is connected to the second power supply line; and a detection circuit which is connected to the bias circuit and compares voltage of the command input terminal with a predetermined voltage value to detect whether input is performed or not, wherein under a predetermined condition, the first switching unit is turned on and the second witching unit is turned off when the detection circuit detects that the voltage of the command input terminal is lower than the predetermined voltage value, and the first switching unit is turned off and the second witching unit is turned on when the detection circuit detects that the voltage of the command input terminal is higher than the predetermined voltage value.
