摘要： A control circuit includes an input terminal for receiving an input signal, which maybe either a digital input signal or an analog input signal, and the control circuit is configured to provide a digital control signal in response to the input signal. The control circuit may include a mode detection circuit for determining whether the input signal is a digital signal or an analog signal and providing a mode signal a multiplexer circuit configured to select either a digital reference signal or an analog reference signal in response to the mode signal, and a comparator configured for comparing the input signal with the reference signal selected by the multiplexer to provide the PWM control signal
