GENERAL DESCRIPTION

APPLICATIONS

WS2803 18-Channel Constant Current LED Driver With Programmable PWM Outputs
● LED decorative lighting
● Indoor/Outdoor LED video or massage display The WS2803 is a constant current LED driver. It is suitable for LED cascading applications. The WS2803 ownes 18 output channels, each channel can drive a constant current up to 30mA. WS2081 contains serial shift registers, data latches, output registers, band gap reference voltage generator, internal oscillator, and programmable constant output current drivers. The serial data is read into the shift registers at the rise edge of the external clock.
