HD108 RGBW pixel LED chip adopt Newstar’s IC to keep long lifespan, top quality/most stable/fastest run speed. What is HD108 LEDs? Upgrade of HD107S, but it is 16-bit 65536 gray, many controller support it, such as Advatek controller, very goods leds to make more colorful LED product. PWM refresh rate: 27kHz, Oscillator frequency: 40Mhz.

1. Product Description 

HD108 RGBW is a two-wire transmission four-channel (RGBW) 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 27KHz, showing more delicate and smooth, the default power does not light. 

2. Feature 

● Top SMD internal integrated high quality external control line serial cascade constant current IC; 5V application; default on electric lights; 

● Control circuit and the RGBW chip in 5050 components, to form a complete control of pixel, color mixing uniformity and consistency; 

● The Two-wire synchronous control, built-in bi-directional transmission function. 

●RGBW four-color output control, 64Bit (65536 level) color settings; each set of data are 8bit start code+56Bit (64) brightness adjustment (red, green, blue and white four ports each 14bits, corresponding to S4 ~ S0) ; 256bits gray data (red, green, blue and whhite 64bits) 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 40MHZ, refresh rate of up to 27KHz, cascade up to 1024 points. 

● REXT external resistance adjusting current (REXT floating, OUTR / G / B / W to about 18mA; REXT external resistor to adjust the maximum current of 60mA).
