Primary-Side Control LED Driv有源PFC的原边控制LED驱动控制器，The CXLE8756 is a primary-side control offline flyback controller with active power factor correction. It is especially designed for LED lighting system

The CXLE8756 is a primary-side control offline flyback controller with active power factor correction. 

It is especially designed for LED lighting system. The CXLE8756 controls the LED current accurately 

without using an opto-coupler, which can significantly simplify the design of LED lighting system. 

Utilizing an on-chip multiplier, the CXLE8756 achieves high power factor over wide line and load ranges.  

The multi-protection function largely enhances the safety and reliability of the system, including over

 voltage protection; short circuit protection, LED open protection, cycle-by-cycle current limit, VCC UVLO

 and over-temperature protection.
