LED driver plays an important role in unleashing many advantages of LED, such as high efficiency, long life-time. A constant current fly-back LED driver based on TOP222 is designed in this paper, and the transformer of the constant current power supply and the constant current feedback circuit are deeply researched. The experiment shows that, the output current of the LED driver is 1A, the output power is 10W, the power supply works in constant voltage mode within the low load situation. The result shows that the driver featured with good stability, constant-current characteristic, and high efficiency, is capable for driving LED.
