Texas Instruments Unveils TLC59282 LED Driver for LED Display Applications

Semiconductor company, Texas Instruments has launched a new 16-channel constant-current sink LED driver that includes a four-channel grouped delay. The TLC59282 streamlines the design in LED display applications such as LED indicators, amusement illumination, message boards and video displays.

The serial-controlled LED driver reduces switching noise by staggering the LED output switching and minimizing the peak switching current transients. This step enables cost-effective two-layer PCB routing of LED modules. The TLC59282 features electromagnetic noise reduction and increased chip-to-chip and channel-to-channel accuracy, which enables even current supply to the LED strings.

The TLC59282 exhibits a maximum LED channel voltage of 17 V with an input voltage range of 3.0 to 5.5 V. The four-channel group delay reduces simultaneous switching noise. The LED driver provides a blank pulse of 30 ns for increased refresh rates for multiplexed applications. It features a cascadable serial communication protocol that enables a display processor in controlling numerous LED drivers on a single serial bus.
