Switching regulator with increased control voltage for generating or stabilizing supply voltage has control stage for increasing control voltage for switching switch on arranged on switch

摘要

The device has a switch (T1) with a current input (1) and output (2) and a control input (3) and a regulation circuit (RS) for producing a control voltage (U2) for the switch. A control stage (C2,C3,D2,D3,R4) for increasing the control voltage for switching the switch on is arranged on the switch. The circuit is coupled to a circuit point whose voltage increases when the switch is switched on.
