SCT2280 - StarChips

SCT2280 16-bit Parallel-In/Parallel-Out Constant Current Driver

The SCT2280 is designed to be a simple but effective solution for lighting LED. It drives up to sixteen LED clusters with regulated constant current for uniform intensity. In applications, an external resistor is used to set the full-scale LED current from 5mA to 60mA. The SCT2280 guarantees each output can endure maximum 7V DC voltage stress. The on/off sta.
