PSR High Precision Constant Current Controller CL1226



GENERAL DESCRIPTION

           CL1226 is a PSR controller with excellent performance, integrating many types of protection functions. CL1226 works in discontinuous operating mode, suitable for the isolated LED driver with input voltage of 85Vac~265Vac and power dissipation of lower than 5W. The system component count is decreased furthest and the chip is offered in DIP8 package, reducing the space which CL1226 occupied. A high precision current sampling circuit is applied in

           CL1226, the output current accuracy can be within ±3%. Besides, CL1226 has LED open/short protection, over current protection (OCP), VDD under voltage lockout (UVLO), etc.
