摘要： A method is provided for driving a plurality of light emitters in a plurality of output paths with each output path including at least one light emitter. The method includes the steps of applying a supply voltage level to a plurality of output paths; generating a current for each path during a period of a predetermined length for the output path; sensing a current level for each output path during the period; comparing each sensed current level with a reference level; increasing the supply voltage level if the sensed current level is lower than the reference level; determining a lowest supply voltage level for the worst case output path; and using the lower supply voltage level as a common supply voltage level for all output paths.

摘要： A method for driving a light-emitting semiconductor is provided. A supply voltage is converted into a secondary output voltage for supplying the light-emitting semiconductor with an output voltage. A level for the supply voltage at the beginning of a high current phase of the light-emitting semiconductor is sensed. A threshold voltage level for the supply voltage level is determined based on the sensed level. The high current phase with the light-emitting semiconductor is stated. The sensed level is continuously compared with the threshold voltage level, and an output current through the light-emitting semiconductor is controlled such that the sensed level does not drop below the threshold voltage level.
