UCS2903 IC Componenets for 12v/24v led strip led module

Short Description:

UCS2903 This pixel protocol was designed by Lianxinke in China, and it is very similar with ws2811/SM16703, and UCS2903 is an improved design of its previous version, UCS1904, offering a constant current design, allowing for a more stable lighting system. The control circuit comes in a SOP8 package, allowing for more flexibility with LED choice.

Support

The UCS2903 is a 3-channel LED display driver / controller with a built-in MCU digital interface, data latches and LED high voltage driving functions. It features superior performances and reliable functions. Under the control of the external MCU, it performs independent grayscale control through data-cascading transfer for driving large outdoor colour dot-matrix LED panels.

Technical Specifications

Clock Type	Data-Only
Color Resolution	8 bits
Physical Package	SOP8
RGB	Yes
RGBW	See UCS2904
Output Pixel Voltage	5 – 24V
PWM Rate	1600Hz

UCS2903 Advantages

Up to 24V, allowing for very long cable lengths
High PWM rate allows for filming these pixels with cameras up to 54fps

UCS2903 Disadvantages

Data-only restricts refresh rates to be limited by the speed of the protocol, which will generally be slow
Only 8 bits of data for each color makes dimming curves less smooth
No redundancy in data
