SK9826-EC20 LED
1. Product Overview :
SK9826-EC20 is a two-wire transmission three-channel (RGB) drive control circuit and light-emitting
circuit in one of the intelligent external control LED light source. Built-in constant current circuit and RC
oscillator; internal integrated current gain control module, CMOS process, low voltage, low power
consumption; when REXT is floating, the three-channel constant current driver default output of 18mA,
the product is equipped with signal decoding module, Can also be REXT external resistor to adjust the
required current, each output channel can output 16 (65536 level) gray adjustable linear current; using
two-wire output, DATA data and synchronous CLK signal, so that the series chip The output action
synchronization; refresh rate up to 4KHz, showing more delicate and smooth, the default power does not
light.
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:
● Chip 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 EC20 components, to form a complete control of pixel,
color mixing uniformity and consistency;
● The Two-wire synchronous control, built-in bi-directional transmission function.
●RGB three-color output control, 64Bit (65536 level) color settings; each set of data are 1bit start code
+15 Bit (32) brightness adjustment (red, green, blue three ports each 5bits, corresponding to S4 ~ S0) ;
48bits gray data (red, green, blue 16bits) composition.
● Three-way constant current drive, built-in high-precision and high stability of the oscillator, current
error <± 5%.
● The maximum serial data input frequency 30MHZ, refresh rate of up to 4KHz, cascade up to 1024
points.
● REXT external resistance adjusting current (REXT floating, OUTR / G / B to about 18mA; REXT
external resistor to adjust the maximum current of 60mA).
