RM9003B single-channel LED constant current drive control chip can directly drive high-voltage LED light string and output current.
The external resistance is set to 5mA~100mA, and the output current is constant at the set value. The chip system has simple structure, few peripheral components and simple circuit.
Application field:
LED fluorescent tubes T5/T8/T10 ...
LED filament lamp/bulb lamp/candle lamp ... Other low-power LED electric light sources.
The peripheral circuit is simple,
No magnetic element is needed.
Multi-chip series or parallel application
Chip can share PCB board with LED.
The LED current can be set externally.
Chip application circuit has no EMI problem.
Built-in 500V high voltage MOS
The chip has the ability of over-temperature regulation.
(Overtemperature point 135 degrees)
Adopt ESOP8 P8, TO252 and SOT89-3 package.
