Abstract

PURPOSE:To simplify the constitution of a pulse width control circuit, by using a voltage comparator having one input terminal of a polarity and a plurality of input terminals of another polarity. CONSTITUTION:A saw tooth wave is inputted to a negative input terminal 40 from an oscillator, and an output of an error amplifier and a DC voltage to set the maximum pulse width are respectively given to positive input terminals 41, 42. If the potential of the terminal 41 is higher than that of the terminal 40, a transistor (TR) 31 is interrupted, and if the potential of the terminal 42 is higher than that of the terminal 40, a TR30 is conductive and a high potential signal is outputted at an output terminal 11. Inversely, if the potential of the terminal 42 is lower, a low potential signal is outputted. Thus, the terminals 41, 42 have a voltage comparison function to the terminal 40, the logical product of compared output is taken to an applied signal, and the number of components for the control circuit can be reduced.
