Datasheet	SCT2168-StarChips.pdf

The SCT2168 serial-interfaced LED driver sinks 8 LED clusters with constant current to keep the uniform intensity of LED displays.

In applications, an external resistor is used to set the full-scale constant output current from 5mA up to 120mA.

The SCT2168 guarantees each output can endure maximum 17V DC voltage stress.

8 constant current sinker with LED power-supply voltage up to 17V Constant output current : 5.
120mA@5V, 3.
80mA@3.3V Excellent current regulation to load, supply voltage and temperature ±1% Current matching between outputs ±3% Current matching between ICs Fast output current control: Minimum PWM pulse width = 120ns All output current are programmed together using a single external resistor CMOS Schmitt trigger inputs with clock rate up to 25MHz Operating supp.
