Abstract
The present invention relates to an electronic device for driving a light emitting diode, which includes a switch (Ts) being adapted to switch a switch-mode power converter, and controlling means (CNTL) being adapted for controlling the switch (Ts) in response to a sensing value (Vs) indicative of a current of the switch-mode power converter and for controlling by the switch (Ts) the output voltage of the switched power converter and a current (Iout) through the light emitting diode.
