Cxle8331 chip is a high precision and high efficiency LED constant current driver and control chip. The constant current accuracy can reach ?5% in the range of full voltage 85vac ~ 265vac input voltage. Cxle8331 chip not only supports the non isolated buck scheme, but also supports the PSR flyback topology. Without any compensation elements, it can achieve constant current output with few peripheral devices, The scheme has low cost. The LED output with built-in self recovery opens short circuit protection circuit to improve the reliability and safety of the system
