    • A control pulse generator according to the present invention includes a voltage generator for generating an output voltage proportional to a power supply voltage, an inverter for generating an inversion signal whose signal level is inverted when the output voltage from the voltage generator reaches a predetermined value, and a pulse signal generator for delaying a level inversion timing of the inversion signal by a predetermined delay time, and generating a control pulse having a width corresponding to the delay time. According to the control pulse generator with the above arrangement, the width of the control pulse can be determined on the basis of the delay time of the pulse signal generator, regardless of rise states of the power supply voltage. In addition, the height of the control pulse can be set at a desired value according to a supply voltage to the pulse signal generator, regardless of rise states of the supply voltage.
