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