LED Driver offers 4-channel grouped delay.
Press Release Summary:
With input voltage range of 3.0-5.5 V and LED channel voltage up to 17 V, Model TLC59282 minimizes simultaneous switching noise by staggering switching of LED outputs, facilitating 2-layer PCB routing in LED modules. Serial-controlled, 16-channel, constant-current sink LED driver features channel-to-channel current accuracy of ±0.6% and chip-to-chip current accuracy of ±1%. Device is suited for video displays, message boards, amusement illumination, and LED indicators.
Original Press Release:
TI Introduces Low-noise 16-channel Constant-current Sink LED Driver
LED driver improves display data integrity on inexpensive PCBs
DALLAS, -- 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
-- Channel-to-channel current accuracy: +/-0.6 percent, typical
-- Chip-to-chip current accuracy: +/-1 percent, typical
Availability and pricing
The TLC59282 is available now in an SSOP package and is priced at $0.47 in quantities of 1,000: www.ti.com/tlc59282-pr. The TLC59282 evaluation module is available on request.
