Product Information

CYT3000B is a high power factor linear constant current high voltage LED driver chip, used in LED lighting field. The chip through a unique constant current control patented technology to achieve constant current accuracy of less than ± 5%, the output current can be adjusted by an external resistor Rt, the chip has a high power factor and low harmonic distortion.

CYT3000B has the output current with temperature automatic adjustment function. When the temperature is too high the system will reduce the output current, in order to achieve the effect of lowering the temperature, the temperature protection point can be set by the external resistance of the pin RTH side.

CYT3000B with input power automatic adjustment function, when the input voltage is too high, it will reduce the output current, the amplitude of the current reduction set by external resistor RD, in order to ensure that the input power does not vary with the input voltage.
