SK9822-EC20(SK9822-2020) is an embedded control type LED light source integrating control circuit and light-emitting circuit. Products containing a signal decoding module, data buffer, a built-in constant current circuitand 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:
● Easy To Design
● Easy To Build
● Easy To Program

3. Description:
● EC LED internal integrated high quality external control line serial cascade constant current IC; 5V
application; default on electric lights;
● 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.
