| Abstract: | The controlling method and the problems of traditional multi-channel LED constant current driver are introduced. A novel LED driver with dynamic output voltage regulation is designed and its working principle is introduced. Through the simulation, the feasibility of the adaptive principle is verified, and finally a low energy consumption multi-channel LED driver whose output voltage changes following up the change in the quantity of LEDs is built. |
