BR5003AG

Description

BR5003AG 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-inover-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 BR5003AG integrates the input line voltage compensation function. When the input line voltage is too high, BR5003AG 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. The BR5003AG expands the application to meet the fractional harmonic requirements.

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.
