CYT4356ZN-2 is a linear constant current IC on high voltage LED chips, used in LED lighting field. Throughr-a-uniquepatented technology and constant current control, the IC can realize constant current precision less than 15%, theoutput current can be regulated by the external Rcs resistor. The IC has high power factor and low harmonic distortion.CYT4356ZN-2 has the function of automatic adjustment of input power. When the input voltage is too high, the outputcurrent will be reduced to ensure that the input power does not change with the input voltage. The chip has simplesystem structure with a variety of protection function without transformer and electrolytic capacitor, the IC use fewperipheral components, can save the space of electronic components, which can realize all SMT processing andfully automatic operation.
