SK9822 LED Chip

SK9822 LED Chip

SK9822 is a new type of IC for 3ch led chips` color dimming control,which has one double signal line-- the data cable and clock cable.After  a series of improvement design,it can well compatible with other two signal IC,and share the same controller system,





More details as below:

1. Product Overview :

SK9822 is a two-wire transmission channel three (RGB) driving intelligent control circuit and the light emitting circuit in one of the LED light source control. Products containing a signal decoding module, data buffer, a built -in constant current circuit and RC oscillator; CMOS, low voltage, low power consumption; 256 level grayscale PWM adjustment and 32 brightness adjustment; use the double output, Data and synchronization of the CLK signal, connected in series each wafer output action synchronization.

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; 5V application; default on electric lights;

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

● The two-wire synchronous control.

The three RGB output control, 8Bit (256) color; 5Bit (32) to adjust the brightness;

● The three constant current drive, self detection function specific signal

● The maximum frequency of 30MHZ serial data input

● The double data transmission, built-in support uninterrupted oscillation PWM output, can maintain a static image.
