SK9822 LED Chip

SK9822 is a new type of IC for 3ch digital rgb led chips` color dimming control,which has one double signal line-- the data cable and clock cable，with faster signal transfer.

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:
