General Description ：
RM9003B is a one_stage LED constant
current driving control chip which
Compatible with silicon controlled dimmer
application.Output current stay a constant
in the range of 5m~100mA as once set by
external SENSE resistor.
It has the advantages of simpler system
structure fewer peripheral components
and simpler circuit.

Applications ：
 LED Fluorescent tube T5/T8/T10…
 LED Bulb/Corn light/Candle lamp…
 Other small power LED lighting…

Features： Simpler peripheral circuit without
magnetic components
 Chips can be used in series or parallel
application
 Chips and LED can be welded inthesame PCB board
 Output current can be set by external
resistor
 Application circuit has no EMI
problems
 Built_in 500V high voltage MOS Over temperature regulation
