Abstract

PURPOSE: To enable to produce the output voltage keeping the relation of a given timing correctly, by controlling the swtching transistor by use of integration circuit and zener diode.
CONSTITUTION: When the power supply voltage A, in which faster in rising at power switch application and slower in falling at disconnection, is supplied, this voltage A is divided at the resistors 2 and 3 and it is fed to the integration circuit 7 consisting of resistors 4 and 5 and capacitor 6, and fed to the base of the switching transistor 9 via the zener diode 8. Thus, the output voltage of the integration circuit 7 is risen by being delayed than the power supply voltage A through integration, and since the base resistor 10 is small, it is fallen quicker than the power supply voltage A. Thus, from the switching transistor 9, the output voltage rising delayed than the voltage A and fallen before it can be obtained easily with simple constitution.
