Abstract
We Designed a buck mode LED driver circuit system, and gave out its schematic drawing and manufactured the IC. From testing results, we confirmed entire design of the circuit system. Compared with traditional LED driver circuit system,the novel LED driver circuit system has improved the line regulation rate and load regulation rate,both can be up to ±1.5%. The external inductance has only a very little influence for the system. When the inductance changes from 100 μH to 200 μH,it will only cause 2% variation on output current.关键词
