The cxle8369 cxle8370 chip is internally integrated with 500V power switch. The working current of the chip is very low. Without auxiliary winding detection and power supply, only a few peripheral components are needed to achieve excellent constant current characteristics, which greatly saves the system cost and volume.
The cxle8369 cxle8370 chip has a high-precision current sampling circuit to achieve high-precision LED constant current output and excellent line voltage regulation. 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.
