Product details

product description

The RM9003A single-channel LED constant current drive control chip can directly drive high-voltage LED light strings. The output current is set to 5mA~100mA by an external resistor, and the output current is constant at the set value. The chip system has a simple structure, few peripheral components and simple wiring.
 

Features

Simple peripheral circuit, no magnetic components required
Multi-chip series or parallel application
Chip can be used with LED PCB board
LED current can be shared externally
No EMI problem with chip application circuit
Built-in 500V high voltage MOS
The chip has over-temperature regulation capability (over-temperature point is 110 degrees)
Available in ESOP8, TO252, SOT89-3 packages
 

Applications

LED fluorescent tube T5/T8/T10
LED filament light/bulb light/candle light
Other low-power LED electric light sources
