BR5004EG

Description

BR5004EG is a four-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 600V lightning surge test when no protection device in the periphery, and built-in over-temperature protection function to improve system application reliability. The output current can be adjusted by adjusting the REXT on the periphery. At the same time, the BR5004EG integrates the input line voltage compensation function. When the input line voltage is too high, BR5004EG 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 is mainly used in the fields of LED lighting, architectural lighting engineering, etc. The system structure is simple, the peripheral components are few, the PCB traces are simple, and the solution cost is low.
