Greeled Electronic LtdGeneralDescription
INK1003 is a constant current LED driver. It is a single line 3-Channel 256 Grey Level Driver.It is
designed for indoor/ outdoor LED displays and decorative LED lighting system. It is suitable for LED
cascading applications. The INK1003 owns 3 output channels, each channel can sink 18.6mA constant
current. INK1003 contains single line data transceiver decoder, data latches, output registers, band gap
reference voltage generator, internal oscillator, and low saturation constant current sinks. The data received
by INK1003 is decoded and then the decoded data is transferred in to the gray level comparator. The output of
the gray level comparator controls the constant output current.
The output polarity reverse function is designed for driving high power LED by adapting the application
circuitry. The single line control scheme reduces the engineering troubles mostly, the special designed input
and output staged of INK1003, make INK1003 survive during output and input pin short with power source or
GND. When 800KHz, it can achieve 1024Pixels cascade connection.
INK1003 is available in both SOP-8 and DIP-8 packages, the operating temperature is -40~85℃.
