3000B Datasheet | Unknown Manufacturer

3000B DATASHEET The product description 3000B is a high power factor linear constant current high voltage LED driver IC used in LED lighting. The chip uses a 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 R1, the chip has a high power factor and low harmonic distortion. 3000B has the function of automatic adjustment of 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 via the external resistor at the RTH pin. Features -...
