Description
The SM6704A is a 4-channel constant current LED driver that has a wide range of output current from 20mA to 180mA per channel and through an external resistor (Rext) to set the maximum sink current which gives users flexibility in controlling the light intensity of LEDs.
Features
- 4-Channel constant sink current.
- Constant output current invariant to load
voltage change.
- Maximum output current per channel up to
180mA.
- Output current adjusted through an external
resistor.
- Excellent output current accuracy :
- Between channels: ±3% , and - Between ICs: ±6% (Max. ).
- Protected functions: - Over temperature (150℃ shutdown IC) - String short circuit detection.
- Low dropout current source (0.6V at 180mA).
- LED output voltage up to 50V.
- S.
