SCT2026 - 16-bit Serial-In/Parallel-Out Constant-Current LED Driver

General Description

The SCT2026 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 90mA.

Key Features

  • 16 constant-current outputs rate at 17V Constant output current range: 5.
  • 90mA Excellent current regulation to load, supply voltage and temperature ±3% Current matching between outputs ±6% 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 triggered inputs High serial data transfer rate: 25MHz Operating supply voltage range of 4.5V to 5.5V Built-in power on res.

StarChips Technology SCT2026 V02_01; Jan/08 16-bit Serial-In/Parallel-Out Constant-Current LED Driver Product Description The SCT2026 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 90mA. The SCT2026 guarantees each output can endure maximum 17V DC voltage stress. The built-in shift registers and data latches making the SCT2026 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.
