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.

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.

摘要： The invention relates to a DC/DC converter operating on the charge pump principle, regulated to a fixed, predetermined output voltage and comprising two charge pump capacitors switched in a switch matrix consisting of nine switches. A control circuit is provided capable of controlling the switches so that the charge pump is changed over between a charging phase and a discharge phase and which is capable of operating the charge pump in two modes having different voltage gain factors (1.5; 2). The regulator comprises furthermore a regulator circuit capable of setting when the charge pump is active in the charging phase in the first mode the ON resistance of a switch present in the charge path of the charge pump capacitors or in the second mode the ON resistances of two switches present each in one of the charging paths of the first or second charge pump capacitor so that the charging voltage presented to the charge pump capacitors in the charging phase assumes the minimum value possible for a specific input voltage of the converter, a measuring circuit capable of defining the voltage occurring at one of the charge pump capacitors at a defined point in time of the charging phase; and a comparator capable of comparing the measured voltage to a predetermined voltage and then when the former attains the latter, changing over the charge pump into the corresponding other mode, wherein the predetermined voltage is selected so that the efficiency of the converter is optimized and the charging condition of the charge pump capacitors is not altered on changeover.

摘要： An unregulated inductorless direct current to direct current converter comprising a first voltage-to-current converter configured to convert a first voltage to a first current and a second voltage-to-current converter configured to convert a second voltage to a second current. A regulation circuit is coupled to the first and second voltage-to-current converters and configured to generate an output current proportional to the difference between the first and second currents. Also a variable frequency oscillator is coupled to the regulation circuit, the oscillator receiving as a control current the output current therefrom and outputting a clock signal having a frequency proportionate to the control current. The converter further comprises an output stage coupled to receive the clock signal and receiving an input voltage and outputting an output voltage, the output voltage and the input voltage having a ratio that is determined by the clock signal.
