Abstract
PURPOSE:To make a separate power source unnecessary by using an output voltage as a source voltage for a control circuit. CONSTITUTION:A chopper type switching regulator is composed of a switching transistor TR1, a rectifying and smoothing circuit RC, a control circuit CT and others. In this case, the source voltage input terminal (a) and reference voltage input terminal (b) of said control circuit CT is connected with an output terminal OUT. Also, said transistor TR1 is driven by a starting circuit KT at the time of starting so that the control circuit CT is started by the output of said transistor TR1, while the transistor TR1 is ON-OFF driven in response to a voltage from a chopping voltage output terminal C after starting. In this manner, because a regulate-controlled output voltage becomes a source voltage for the control circuit CT, a reference voltage generated on the basis of said source voltage varies little so that a regulate-action is stabilized.
