For the remote control of multi-channel high power LEDS, a high-precision LED current control system is proposed. A microcontroller system based on STM32F217ZET containing a four-channel high power LED driver circuit based on LT3755-1 was designed. The high-precision current control compensation algorithm is presented, which divides the current control function into three parts and adds proportionality and shift coefficients to the function, improving the current control accuracy from 25% to ±1%. The output current of each channel can be continuously adjusted from 200mA to 1800mA, with the single channel output power able to reach 90W and the output voltage able to reach 50V. The system proposed can be monitored via TCP/IP through the remote PC interface.
