CYT3000BM 替代CYT4356ZN 三段线性恒流驱动芯片

CYT3000BM is a linear constant current IC on highvoltage LED chips, used in LED lighting field.Through a unique patented technology andconstant current control, IC CYT3000BM canrealize constant current precision less than ±5%,the output current can be regulated by the externalRCS resistor. The IC CYT3000BM with high powerfactor and low harmonic distortion.CYT3000BM have the function of the output currentwith the temperature automatic adjustment. Whenthe temperature is too high, it will reduce the outputcurrent, in order to achieve the effect of lowering thetemperature, temperature protection point can setthrough the pin RTH's external resistance.CYT3000BM has the function of the input powerautomatic adjustment when the input voltage is toohigh, it will reduce the output current, reduce themagnitude of the current through the externalresistors RD Settings, to ensure the input powerdoes not change with the input voltage Simplesystem structure, the IC CYT3000BM has a varietyof protection function without transformer andelectrolytic capacitor, the IC CYT3000BM use fewperipheral components, can save the space ofelectronic components, which can realize all SMTprocessing and full automatic operation.
