A 500V power device is integrated in the chip. The peripheral application can achieve high precision constant current without auxiliary winding detection and power supply, which greatly reduces the external cost. Cxle83120 has a variety of constant current auxiliary functions to achieve excellent linear compensation and high-precision constant current effect. Cxle83120 works in the inductive current critical continuous mode (TM). The output current does not change with the change of inductance and load, and it has excellent load adjustment characteristics. The cxle83120 integrates multiple protection functions, greatly enhancing the reliability of the system. The protection functions include LED open circuit protection, led short circuit protection, undervoltage locking, current sampling resistance short circuit protection and over temperature regulation
