Cxle8327 chip adopts the patented drive and output detection mode. The working current of the chip is very low. It does not need auxiliary winding detection and power supply. It only needs a few peripheral devices to achieve excellent constant current output and linear adjustment rate, which greatly saves the system volume and cost. Scxle8327 chip works in the critical continuous mode of inductance current, the output current does not change with the inductance and the working voltage of LED, and achieves excellent load regulation rate. Scxle8327 has multiple protection functions, including LED on / short circuit protection, hvdd under voltage protection, over temperature protection, etc.
