CYT1002AG single-segment line voltage pensation linear constant current LED control chip General Description CYT1002AG is a dual-channel high-voltage single-segment line voltage pensation linear constant-current LED driver chip, which is used in LED lighting field. The chip achieves a constant current accuracy of less than 4% through a unique patented constant current control technology. With the linear constant current technology, the output current sets the driving current of the LED light string through an external resistor. CYT1002AG has the function of line voltage pensation, which automatically reduces the output current when the input voltage is too high, so as to ensure that the input power does not change with the input voltage and ensure the heat dissipation stability of the system. Electric Characteristics Unless otherwise stated, T A=25°C.
