Based on the patented linear step-down constant current drive technology, cxle86190 allows the LED voltage to be less than half of the peak AC voltage, and can achieve good performance

Based on the patented linear step-down constant current drive technology, cxle86190 allows the LED voltage to be less than half of the peak AC voltage, and can achieve good performance with a power factor greater than 0.8 and an efficiency greater than 80%. It overcomes several shortcomings of the traditional linear LED driver.
Cxle86190 has built-in two-way switch constant current source and mains phase detection circuit, forming different electrical connection relations and working modes between LED load and energy storage capacitance in different phases of mains power. In a power cycle, the LED load flows through the charging current and discharge current respectively, which makes the LED current fluctuate at the frequency of 4 times of the power frequency, reducing the visual flicker of the human eye; by limiting the charging current, a higher power factor is achieved; the cxle86190 can also operate within the input range of 120 / 230VAC global power grid, and always maintain a higher efficiency and power factor.

Based on the patented linear step-down constant current drive technology, cxle86190 allows the LED voltage to be less than half of the peak AC voltage, and can achieve good performance
