DALLAS, Feb. 16, 2011 /PRNewswire/ -- Texas Instruments
Incorporated (TI) (NYSE: TXN) today introduced a serial-controlled,
16-channel constant-current sink LED driver with four-channel
grouped delay. This device simplifies design in LED display
applications, including video displays, message boards, amusement
illumination and LED indicators. For samples and technical
documentation, see: 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.
- Cascadable serial communication protocol allows a display
processor to control multiple LED drivers on the same serial bus.
Precision current matching aids uniform LED brightness between
strings.
- 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.
Availability and pricing
The TLC59282 is available now in an SSOP package and is priced
at $0.47 in quantities of 1,000:
