CYT3000B is a high power factor linear constant current high voltage LED driver chip, used in the field of LED lighting. The chip passes 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 RCS.
The chip has high power factor and low harmonic distortion.
The CYT3000B has the function of automatically adjusting the output current with temperature. When the temperature is too high the system will reduce the output current to reach To reduce the temperature effect, the temperature protection point can be set by the external resistor on the pin RTH terminal.
CYT3000B with input power automatic adjustment function, when the input voltage is too high, will reduce the output current, current drop The low amplitude is set by the external resistor RD, thus ensuring that the input power does not vary with the input voltage. Can be achieved AC180V to AC300V input voltage range, the input power change within 5%.
