TI launches full-color display with 16 channel LED driver

TI launched a 16 channel, a constant current sink LED drive under 50 mA, the output voltage of 17 volts. TLC5943 integrates enhanced spectral pulse width adjustment to improve image quality and reduce flicker noise in monochrome, multicolor and full-color LED displays.

The 16 channel of each TLC5943 has an independent adjustable automatic data refresh and display repeat function of the 16 level gray scale pulse width adjustment brightness control. Channels are divided into 4 groups. Each group has an associated turn-on delay time to maximize the system voltage stability. The designer can use an external resistor to set the maximum current value for all channels.

Brightness control features can be achieved through a common 30-MHz interface. The average current level is adjusted to compensate for the change in brightness of LED from one to the other.

Price and availability

The TLC5943 is now available in 28 pin HSSTOP package or a 32 pin QFN package. Number 1000 when HSSTOP package recommended retail price of $2, QFN package for $2.20.
