CYT3000B High Power Factor Linear Constant Current LED Chip CYT3000B Specification Product Description
CYT3000B is a high power factor linear constant current high voltage LED driver chip used in the field of LED lighting. The chip adopts a unique patented constant current control technology to achieve a constant current accuracy of less than ±5%, and 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 achieve the effect of lowering the temperature. The temperature protection point can be set by the external resistor at the RTH end of the pin.
The CYT3000B has an automatic input power adjustment function. When the input voltage is too high, the output current will be reduced. The current reduction is set by the external resistor RD to ensure that the input power does not change with the input voltage. It can realize the input voltage variation range of AC180V to AC300V input voltage within 5%. The system has simple structure, various protection functions such as over-temperature and over-voltage, and built-in 750V high-voltage constant-current MOS to improve the reliability of the product. The solution does not require transformers and electrolytic capacitors. Very few external components save space in electronic components. The scheme is simple in design, easy to debug and easy to install. High conversion efficiency (90%), high PF value (greater than 0.98). Suitable for standardization, automation, and mass production. Features No need for transformer and electrolytic capacitor integration High-voltage start-up Power supply output current adjustable up to 80mA Inter-chip current deviation <±5% Power factor >0.98 Package form ESOP8 with automatic temperature adjustment function Power automatic adjustment function Chip application system No EMI problem efficiency :>90% THD: <20%
