CYT3000BS 三段高壓LED線性恒流驅動芯片
CYT3000BS is a linear constant current IC on high voltage LED chips, used in LED lighting field. Through a unique patented technology and constant current control, IC CYT3000BS can realize constant current precision less than ±5%, the output current can be regulated by the external Rcs resistor. The IC CYT3000BS with high power factor and low harmonic distortion.
CYT3000BS have the function of the output current with the temperature automatic adjustment. When the temperature is too high, it will reduce the output current, in order to achieve the effect of lowering the temperature.
CYT3000BS has the function of the input power automatic adjustment when the input voltage is too high, it will reduce the output current, reduce the magnitude of the current through the external resistors Ro Settings, to ensure the input power does not change with the input voltage
Simple system structure the IC CYT3000BS has a variety of protection function without transformer and electrolyic capacitor, the IC CYT3000BS use few peripheral components, can save the space of electronic components, which can realize all SMT processing and full automatic operation.
No transformer and electrolytic capacitor are needed.
