StarChips Technology SCT2024 V01_03; May/11 16-bit Serial-In/Parallel-Out Constant-Current LED Driver Product Description The SCT2024 serial interfaced LED driver sinks 16 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 45mA. The SCT2024 guarantees each output can endure maximum 17V DC voltage stress. The built in shift registers and data latches making the SCT2024 effective solution in driving LED display. The output enable function gates all 16 outputs on and off, and is fast enough to be used as PWM input for LED intensity control.
