CYT3001BS 三段高壓LED線性恒流驅(qū)動芯片
CYT3001BS is a three-segment LED linear constant current control chip with high power factor. It integrates 700V high voltage MOSFET, and adopts unique and innovative device process technology, with superior resistance to avalanche breakdown and surge. It can pass 650V lightning surge test when no protection device in the periphery, and built-in overtemperature protection to improve system application reliability. The peripheral can accurately set the output LED current through the external resistor, and it can reduce THD by optimizing the voltage reference when the segment is tumed on.CYT3001BS integrates the input line voltage compensation. When the input line voltage is too high, CYT3001BS will reduce the output current according to the external compensation resistor to ensure that the input power does not change with the line voltage.
It internally optimizes the wiring and facilitates routing when multiple chips are connected in parallel, saving jumper resistance.
It is mainly used in the field of LED lighting. The system structure is simple, the peripheral components are few, the PCB traces are simple, and the solution cost is low.
