General Descriptions of LC8808 LED
The LC8808 is a 3-channel constant current LED drive with resumable data transfers and internal display patterns. There are three open-drain constant current outputs, with a build-in PWM of gray scale. The range of input power is from +9V to +15V, and voltage-endurance of LED port is +12V. There is a built-in 12bits GAMMA correction module. PWM maximum refresh frequency is 8kHz,The LC8808 use the e-RZ (extended return to zero code) as the signal transmission mode, which can control the output current channel by channel and cascade infinitely.LC8808 provides two-signal data input as redundant control, which ensures the transmission of the signal if any single chip damages. In the absence of signal input,LC8808 displays the built-in display patterns that is suitable for those applications without a controller. There is the built-in power-on and power-off protection in the drive, which can enhance the service life of the chip. It also has the automatic test function while power on, which is convenient for the customer to test,The LC8808 provides SOP8 packaging, working environment is from -40 ° C to + 85 ° C.

sk6805-2427 smallest digital rgb led chip

SK6805-2427 smallest digital rgb led chip


Introduction of SK6805-2427:

SK6805 2427 is one of the smallest digital rgb led chip for the moment,with the small size 2.4*2.7*1.1mm, it can be use to developed P3 HD led display,also can be the super narrow pcb strip lights with 3mm width pcb,also can be high density as high as 250 led/m led strips.With the milky gel inside the led,which is good for our eyes ,and can be friendly use for the children`s toys.The SK6805-2427 can be greatly increase the application of digital led lights.

1. Product Overview :
SK6805-2427 is a smart LED control circuit and light emitting circuit in one controlled LED source, D 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 unipolar 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.

2. 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.. 3. Description:
● Top SMD internal integrated high quality external control line serial cascade constant current IC;
● control circuit and the RGB ch m 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 Kbps, when the refresh rate of 30 frames per sec

General Description
WS2815-MINI is an intelligent control LED light source that the control circuit and RGB chip are integrated in a
package of 3535 components,outlook is the same as 5050 LED;Any components is a pixel;Its internal includes
intelligent digital port data latch and signal reshaping amplification drive circuit.Also include a precision internal
oscillator and a programmable constant current control part,which achieves highly consistent color effect.Realize double
signal transmission,if any pixel failure,it won’t affect the whole display;
The data transfer protocol use single NZR communication mode. After the pixel power-on reset, the DIN port
receive data from controller, the first pixel collect initial 24bit data then sent to the internal data latch, the other data
which reshaping by the internal signal reshaping amplification circuit sent to the next cascade pixel through the DO port.
After transmission for each pixel, the signal to reduce 24bit. Every pixel adopts auto-reshaping transmit technology,
making the pixel cascade numbers are not limited to the signal transmission, only relate to the speed of signal
transmission.
The BIN receives the data signal, and then compare the data with the DIN side after phagocytosis of 24bit data, if
DIN do NOT receive the signal, then switching to BIN for receiving the input signal, which ensure that any the IC's
damage does not affect the signal cascade transmission and make the BIN in state of receiving signal until restart after
power-off.
Refresh Frequency updates to 2KHz, Low Frame Frequency and no Flicker appear in HD Video Camera.
300us or more of reset time, it won’t cause wrong reset while interruption, it supports the lower frequency and

inexpensive MCU.
