1. Product Overview :
SK9810-EC15 is an intelligent external control LED light source with one line transmission
three channel (RGB) drive control circuit and light-emitting circuit. The product contains signal
decoding module, data buffer, built-in constant current circuit and RC oscillator; internal
integrated current gain control module, CMOS process, low-voltage and low power
consumption; three channel constant current driver default output of 9ma, using single line
output mode, the output of each chip in series is synchronous; the light is not on by default
when power on. The data protocol adopts unipolar return code communication mode, single line
transmission LED driver control chip, and the chip has built-in current gain adjustment function,
which can set current 0.25ma ~ 9.0ma, a total of 16 current gain levels;
Channel data output 16 bit gray data, output real 65536 levels. The refresh rate of PWM signal is
as high as 4kHz, which makes the display more delicate and smooth, and solves the problem of
dark stripe in the picture;
2 . Main Application Field:
● LED full-color light string, led full-color module, led magic soft and hard light strip, LED
guardrail tube, led appearance / scene lighting
● LED point light source, LED pixel screen, led special-shaped screen, all kinds of electronic
products, electrical equipment, racing lamp..
3. Description:
● Chip SMD internal integration of high-quality serial cascade constant current IC; 5V power
supply application; default power on does not light up; built-in power supply regulator circuit;
● The control circuit and chip are integrated into EC1515 components to form a complete
external control pixel. The color temperature effect is uniform and consistent;
●Single line synchronous control, built-in unidirectional transmission function, cascade data
shaping output; prevent data attenuation;
●4 bits current gain adjustment bits of outr / g / B and gray level adjusting circuit;
●Three way constant current drive, built-in high precision and high stability oscillator, current
error < ± 5%;
● Built in PWM patent technology, refresh rate up to 4kHz, signal transmission rate up to
800kbps;
● Data transmission mode: trst + 1st 48bits + 2nd 48bits + +N 48bits + 16bit current gain data +
reset data, current gain data, when sending current gain data, it is necessary to send 16bits
current gain adjustment bit; when sending RGB three color current gain bit, 4bits gain data of
reserved bit is also filled in randomly, but cannot be empty; any data can be sent;
● Product support supports dynamic energy saving mode (automatic start stop);
●The product supports ultra-low power standby mode.
