Abstract
A control circuit comprising a driving circuit, which comprises a voltage adjusting circuit for generating a control voltage, and comprises a first transistor and a second transistor. The first transistor comprises: a first terminal; a second terminal; and a control terminal, for receiving a bias voltage generated from at least operating voltage of the control circuit. The second transistor comprises: a first terminal, coupled to a second terminal of the first transistor; a second terminal, for receiving a first predetermined voltage; and a control terminal, for receiving the control voltage. The control circuit further comprises: a candidate voltage selecting circuit, for outputting one of a plurality of candidate voltages; and a voltage selecting circuit, for outputting one of the candidate voltage output from the candidate voltage selecting circuit and a ground voltage as the bias voltage.
