Cxle83110 high precision step-down LED constant current controller with source power factor correction which is suitable for the non isolated step-down LED constant current power supply

Cxle83110 integrated active power factor correction circuit can achieve high power factor and low total harmonic distortion. Due to the operation in the critical continuous mode of inductor current, the power MOS transistor is in the zero current on state, the switching loss can be reduced, and the utilization rate of inductor is also high.
Cxle83110 integrates 500V power MOSFET internally, and only needs a few peripheral devices to achieve excellent constant current characteristics. Cxle83110 adopts patented floating structure to sample inductor current in full cycle, which can realize high-precision output constant current control, and achieve excellent line voltage adjustment rate and load adjustment rate
