Product Overview :

SK6812 is a smart LED control circuit and light emitting circuit in one controlled LED source, which has the shape of a 5050 LED chip. Each lighting element is a pixel, and the intensities of the pixels are contained within the intelligent digital interface input. The output is driven by patented PWM technology, which effectively guarantees high consistency of the color of the pixels. The control circuit consists of a signal shaping amplification circuit, a built-in constant current circuit, and a high precision RC oscillator.

The data protocol being used is uni-polar NRZ communication mode. The 24-bit data is transmitted from the controller to DIN of the first element, and if it is accepted it is extracted pixel to pixel. After an internal data latch, the remaining data is passed through the internal amplification circuit and sent out on the DO port to the remaining pixels. The pixel is reset after the end of DIN. Using automatic shaping forwarding technology makes the number of cascaded pixels without signal transmission only limited by signal transmission speed.

The LED has a low driving voltage (which allows for environmental protection and energy saving), high brightness, scattering angle, good consistency, low power, and long life. The control circuit is integrated in the LED above.

Main Application Field:

Full color LED string light, LED full color module, LED super hard and soft lights, LED guardrail tube, LED appearance / scene lighting

LED point light, LED pixel screen, LED shaped screen, a variety of electronic products, electrical equipment etc..

Description:

Top SMD internal integrated high quality external control line serial cascade constant current IC;

Control circuit and the RGB chip in SMD 5050 components, to form a complete control of pixel, color mixing uniformity and consistency;

Built-in data shaping circuit, a pixel signal is received after wave shaping and output waveform distortion will not guarantee a line;

The built-in power on reset and reset circuit, the power does not work;

Gray level adjusting circuit (256 level gray scale adjustable);

Red drive special treatment, color balance;

Line data transmission;

Plastic forward strengthening technology, the transmission distance between two points over 10M;

Using a typical data transmission frequency of 800 K bps, when the refresh rate of 30 frames per sec

Package Dimensions:

The Electrical Parameters
(unless otherwise specified,VDD=5V,TA=25℃)

Switching Characteristic
(unless otherwise specified,VDD=5V,TA=25℃)

Coding Description
The chip protocol uses a unipolar zeroing code,every code element must have a low level.
Each code element of this protocol starts with a high level,a high level time width determines '0' code or '1' code.

 Shipment:
Shipment by Express: DHL,UPS,FEDEX,we working wth their for more than 5 years,so we can get the best price with best service.

Shipment by Air: considering the expensive international freight,shipment by air is a good choice if the goods more than 100KG,note:it is door to airport,you need pick up the goods at airport.

Shipment by Sea: It is cheapest shipment way,people always choose it when the goods weight more than 1-2CBM at least,it is door to port,you have to pick up the goods at port.
