发明名称 A soft start circuit
摘要 To eliminate overshoots of an output voltage from a DC/DC voltage converter (1) during start-up of the converter as well as during recovery after a short-circuit of a first and a second output terminal (5,5') of the converter, a circuit (R2, R3, R4, C1, D2) is provided for generating, during a predetermined interval, a signal that is proportional to the rate of increase of the output voltage of the converter (1) to be supplied to the input of an error amplifier (4) to be superimposed on an error signal corresponding to a difference between an actual value and a set desired value of the output voltage of the converter (1), supplied to a control circuit (3) controlling the converter (1).
