RM9003X is a single channel LED constant current drive control chip, which can directly drive high voltage LED string and integrate 600V high voltage MOS tube. The output current can be set by the external resistor in the range of 5 mA ~ 100mA, and the output current does not change with the input voltage. RM9003X series chip application line is simple and has few external components. The program cost is low.
Simple peripheral circuit, without magnetic components
More chips in parallel application
LED current can be set externally
Application solutions without EMI problems
Have a overtemperature adjusting function
The filament lamp, ball bubble lamp, such as T torch LED lamps and lanterns.
