ELECTRIC DRIVER CIRCUIT FOR DRIVING A LIGHT-EMITTING DIODE AND METHOD THEREOF

摘要

An electric driver circuit (100) for driving a light-emitting diode 20 may be operated in a regulation operation mode to generate an output voltage (Vied) to drive a predefined current through the light- emitting diode (20). The electric driver circuit (100) is operated in a start-up operation mode before the regulation operation mode. The operation of the electric driver circuit (100) in the start-up operation mode enables that a coil current generated in an inductor (40) can be completely discharged before starting the regulation operation mode.
