Cxle86168 is a high-precision step-down LED constant current driver chip. The chip works in the critical continuous mode of inductor current, and is suitable for the non isolated step-down LED

Cxle86168 is a high-precision step-down LED constant current driver chip. The chip works in the critical continuous mode of inductor current, and is suitable for the non isolated step-down LED constant current power supply of 85vac ~ 265vac full range input voltage. The cxle86168 chip is internally integrated with 500V power switch. It adopts special driving and current detection methods. The working current of the chip is very low. It does not need auxiliary winding detection and power supply, only needs a few peripheral components, so it can achieve excellent constant current characteristics, greatly saving the cost and volume of the system. The cxle86168 chip has a high-precision current sampling circuit, and adopts constant current control technology to achieve high-precision LED constant current output and excellent line voltage regulation rate. The chip works in the inductive current critical mode, the output current does not change with the inductance and the LED working voltage, achieving excellent load regulation
