Overview

® RT8456 Isolated Secondary Side LED Lighting Current Controller General Description The RT8456 is an isolated secondary LED current controller designed specifically for lighting fixtures such as E27, GU10, T5 and T8.
The IC is suitable for applications that require power line isolation for safety and reliability, high conversion efficiency, as well as high LED current accuracy.
The RT8456 contains 1) a constant current regulating amplifier with 59mV threshold used to program the LED string current with a simple resistor to within 5% LED current accuracy; 2) an over voltage comparator to protect the output when LED string is open or broken; 3) and an opto-coupler driver to control the prima...
