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 1):
A semiconductor device for power supply control which generates and outputs a driving pulse for performing control to turn on or off a switching element which intermittently makes current flow to a primary-side winding wire of a transformer for voltage conversion, by inputting voltage in proportion to current flowing in the primary-side winding wire of the transformer and an output voltage detection signal from a secondary side of the transformer, the semiconductor device comprising:\n a high-voltage input start terminal to which alternating-current voltage of AC input or voltage rectified in a diode bridge is input; a plurality of 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 a plurality of reference voltages that are different from each other; a timer circuit which starts to measure a predetermined time at a timing of rising and/or falling of output of the plurality of voltage comparison circuits; and a discharging unit which is provided between the high-voltage input start terminal and a ground point, wherein when the timer circuit measures the predetermined time, the discharging unit is made conductive.
