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.
