SLED1733 series have four types of built-in LED matrix. The chip can drive up to 256
LED lights and 75 RGB LED lights. In the LED matrix of SLED1733 series, each LED has
on / off, blinking, breathing light and audio input, automatic synchronization and
many other functions. The PWM (pulse width modulation) technology incorporated in
the chip can provide 256-level brightness adjustment and it also equipped with 16-level
dot correction function. In addition, SLED1733 also supports automatic detection technology
and two stage of temperature detectors.
SLED1733 series with the features of multi-channel, constant current and PWM.
The SLED1733 provides per channel constant current range from 8mA to 40mA, and the
output current channel can be adjusted through the 64-level internal register. The
series also supports 2.7V to 5V power supply system and the sink current is up to
320mA per output channel.
