Description
INK1002 is a digital full color SMD5050 LED,which integrates high quality LED chips and INK1003
single-wire cascadable LED driver IC in a small SMD5050 LED package. Its dimension is the same as the
usual SMD5050 LED. The high uniformity driver IC INK1003 ensures the low deviation of this digital LED.
The communication protocol of INK1002 is “AUTO-ZERO” code. Once the chip is reset, DI PIN is ready
to receive gray level data transferred by the controller, when the first 24-bit data package is received by the
first chip, the later received data will be reconstructed by the chip and transferred from DO PIN after about
150nS delay to the next chip. With this method, the cascading LED lamps are unlimited, only limited by the
data transferring rate.
INK1002 is low voltage driver, friendly to environment, high efficacy, long life time, and the application
board is also minimized, easier for user. Its operating temperature range is -40~85℃。
