Abstract :
The author believe that White LED will be used widely because of its low calorific value, small power consumption, long service life, fast response, and so on. Most of its driver chips use voltage mode or current mode control circuit. Current mode white LED driver circuit is studied more for its linear adjustments and good load regulation. This paper proposed a white led driver using LN2117 series chips, and experiment results verify that the chip has good performance.
