ABSTRACT:
In satisfying the above need, as well as overcoming the enumerated drawbacks and other limitations of the related art, the present invention provides an improved switched driver circuit. As disclosed above, there is a need to compensate for the high impedance load characteristics in certain implementations of hysteretic switching constant current drivers. The switching waveform of switching constant current driver circuits may be modified in such a way that retains the important dither characteristics and improves system level performance.
