RM9003B
Description
：
RM9003B is a one_stage LED constant current driving control chip which patible with silicon controlled dimmer application.Output current stay a constant in the range of 5m~100m A as once set by external SENSE resistor. It has the advantages of simpler system structure fewer peripheral ponents 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 ponents
- Chips can be used in series or parallel application
- Chips and LED can be welded in the same 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
- Package：ESOP8、TO252、SOT89-3
