-Data Sheet
* General Description
RM9003E is a one_stage LED constantcurrent driving control chip which can beused to drive high voltage LED stringsdirectly.
Output current stay a constant inthe range of 5m~60mA as once set byexternal SENSE resistor.It has theadvantages of simpler systemstructure,fewer peripheral componentsand simpler circuit.
* Features
1. Simpler peripheral circuit withoutmagnetic components
2. Chips can be used in series or parallelapplication
3. Chips and LED can be welded in thesame PCB board
4. Output current can be set by externalresistor
5. Application circuit has no EMIproblems
6. Built_in 400V high voltage MOS
7. Over temperature regulation
8. Package:ESOP8
