Cxle8410 system works in the voltage mode control, through the fixed conduction time control, we can get high power factor. The chip has built-in UVLO function, which can ensure the normal and stable operation of the system through large hysteresis voltage. Cxle8410 integrates complete protection functions, including cycle by cycle current limiting protection, output over-voltage protection, output short circuit protection and over temperature protection, to ensure reliable operation of LED power supply. Cxle8410 is a single-stage, high power factor AC-DC LED constant current driver chip based on the original edge feedback technology. Only a few peripheral components are needed to control the LED current accurately, without optocoupler and secondary feedback circuit
