Cxle86175 is a high precision step-down LED constant current control chip with source power factor correction, which is suitable for the non isolated step-down LED constant current power

Cxle86175 is a high precision step-down LED constant current control chip with source power factor correction, which is suitable for the non isolated step-down LED constant current power supply with 85vac-265vac full range input voltage. Cxle86175 integrated active power factor
Digital 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. Cxle86175 adopts floating structure to sample inductance current in full period, which can realize high precision output constant current control, and achieve excellent line voltage regulation rate and load regulation rate
