摘要： A non-synchronous boost converter includes a low-voltage device connected between the input voltage terminal and the output voltage terminal of the converter. When the converter is shutdown, the low-voltage device disconnects the output voltage terminal and the input voltage terminal. Since it is a low-voltage device used in the converter for load disconnection, the efficiency of the converter is improved with lower cost.

摘要： A control device, which controls a power-converting module that is coupled to a light-emitting component, includes a duration detecting unit and a control signal generator. The duration detecting unit compares the duration of a predetermined logic state of a pulsating input dim control signal with a reference time period. The control signal generator is enabled by the duration detecting unit so as to generate a control signal that enables the power-converting module to generate a drive voltage for driving the light-emitting component when the duration of the predetermined logic state is not longer than the reference time period. The duration detecting unit disables the control signal generator to disable the power-converting module when the duration of the predetermined logic state is longer than the reference time period.
