Cxle83121 cxle83122 is an excellent step-down constant current driver chip, which can realize high-precision LED constant current driver. The chip works in the inductive current critical

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.
Cxle83121 cxle83122 has a variety of constant current auxiliary functions to achieve excellent linear compensation and high-precision constant current effect. Cxle83121 cxle83122 works in the inductive current critical continuous mode (TM), the output current does not change with the change of inductance and load, and has excellent load adjustment characteristics.
Cxle83121 cxle83122 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

Cxle83121 cxle83122 is an excellent step-down constant current driver chip, which can realize high-precision LED constant current driver. The chip works in the inductive current critical
