SK9822-A 5050 RGB Addressable LED Chip
Model: SK9822-A
SK9822-A is the upgrade type of SK9822, PWM refresh rate can be 27kHz, Oscillator Frequency is more than 30MHz.
SK9822-A RGB LED chip is same with SK9822 with a type ic for the three-color RGB Diming control strip and string ,This ic using the CMOS process to provide three-color RGB LED output driver to adjust the output with 256 gray scale and 32 brightness adjustment,SK9822-A RGB LED diodes with 2 signal output way, one is clock ,another is data, the clock and data is synchronizated ,so that the crystal cascade piece of output movement is sychronizated.
1. Product Overview :
SK9822-A 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.
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.
