The cxle8330 chip is internally integrated with 500V power tube, and adopts the patented drive and output detection mode. The chip has a very low working current and does not need auxiliary winding detection and power supply, Only a few peripheral devices are needed to achieve excellent constant current output and linear regulation rate, which greatly saves the system volume and cost. Cxle8330 chip works in the critical continuous mode of inductive current, the output current does not change with the change of inductance and led working voltage, and achieves excellent load regulation rate. Cxle8330 has multiple protection functions, including LED on / short-circuit protection, Hvdd under voltage protection, over temperature protection
