TI introduces low-noise 16-channel constant-current sink LED driver

DALLAS Feb. 16, 2011 www.ti.com/tlc59282-pr

The TLC59282 minimizes simultaneous switching noise by staggering the switching of the LED outputs, lowering the peak switching current transients facilitating low-cost, two-layer printed circuit board (PCB) routing in LED modules. With traditional multichannel LED drivers, four-layer PCB routing is required to prevent switching transients from causing corruption of the serial data communication path during output blanking. In addition to electromagnetic noise reduction, the TLC59282 has high-precision channel-to-channel and chip-to-chip accuracy, which ensures that uniform current is supplied to each LED string.

Key features and benefits of the TLC59282

  • 3.0-V to 5.5-V input voltage range.
  • LED channel voltage up to 17 V.
  • Four-channel group delay minimizes simultaneous switching noise.
    • Channel-to-channel current accuracy: +/-0.6 percent, typical
    • Chip-to-chip current accuracy: +/-1 percent, typical
  • 30-nanoseconds blank pulse allows for high refresh rates in multiplexed applications.
