摘要
The present disclosure relates to a capacitor step-down LED driver and a driving method using the same. A capacitor step-down LED driver comprises a control circuit and a switching circuit. The control circuit turns on or off the switching circuit in response to an output current and an output voltage of the capacitor step-down LED driver, and thus controls an amount of energy supplied from an input side to an output side. In a first operation state, the switching circuit is controlled not to supply energy from the input side to the output side. In a second operation state, the switching circuit is controlled to supply energy from the input side to the output side. Thus, the output current is maintained to be a value of a desired driving current.
