SCT2024

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. Since the serial data input rate can be reached up to 25MHz, the SCT2024 will satisfy system which needs high volume data transmission to control the LED display. Furthermore, the SCT2024 provides excellent temperature regulation thus it can be applied to varied of operating temperature. Features 16 robust constant current sinker with LED power supply voltage up to 17V Constant output current : 5 – 30/[email protected]/5V Wide power supply voltages: 3.3V to 5V Excellent regulation to load, supply voltage and temperature Temperature regulation: ±0.005%/°C, Load regulation: ±0.1%/V Line regulation: ±0.5%/V High current matching accuracy: ±1% between outputs, ±2% between ICs Fine grayscale response with 180ns PWM pulse width Dropout voltage 0.5V@20mA, VDD=5V CMOS Schmitt trigger inputs with clock rate up to 25MHz ...
