ABSTRACT:
A starting circuit and a method for stagedly starting an electrosensitive circuit without introducing a surging current are disclosed. The method includes (a) providing a feedback signal by the electrosensitive circuit, (b) comparing the feedback signal with a reference signal to generate a control signal, and (c) stagedly increasing a current inputted into the electrosensitive circuit according to a voltage of the control signal so that the electrosensitive circuit is stagedly started without introducing the surging current. The starting circuit includes a comparing circuit for receiving a feedback signal from the electrosensitive circuit and comparing the feedback signal with a reference signal to generate a control signal, and a controlling circuit for controlling the electrosensitive circuit to be stagedly started according to the control signal without introducing the surging current.
