number of super capacitors 316 may be placed in series and or parallel combinations in order to apply the same methods this configuration 300 is shown in fig3 additionally those skilled in the arts should recognize that multiple driver combinations may be used in parallel wherein multiple loads 418 may be driven from the same super capacitor or combination of super capacitors 416 as illustrated in fig4 differences in forward voltages among individual load components may require different duty cycles for each resulting in sudden differences in supply voltage for example in the event one led in a load of multiple leds is turned off before its neighbor however since many switching cycles are used during a flash event this problem is greatly diminished further variations in the circuitry shown and described in the exemplary embodiments may be introduced within the scope of the invention for example a sense resistor may be used in series with the driver transistor in order to accurately measure the current at that point the resistor value is preferably kept very small since there is only one large current value required an improvement in system efficiency may also be realized in some applications by implementing direct drain current sensing of the driver transistor again since there is only one large value of average load current required this can be achieved using ic design techniques known to those skilled in the arts if an integrated driver transistor is employed in another example of a preferred embodiment illustrated in fig5 in applications where it is desirable for flash leds to also be used in a sustained mode e g as a flashlight instead of using a large driver transistor.
