            • SK9816MICRO LED


              1. Product Overview :

              SK9816MICRO(SK9816-2427) is an intelligent external control LED light source that integrates a single-wire transmission three-channel (RGB) drive control circuit and a 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, low power consumption; default output of three-channel constant current driver is 19mA, single-wire output is adopted, The output actions of each chip in series are synchronized; the power-on default is no light. Unipolar NRZ data protocol of communication, the transmission-line LED driving control dedicated chip, while the chip built-in current gain adjustment function, setting the current 1.75mA ~ 19mA, a total of 16 current gain levels; refresh rate of the PWM signal is high 4KHz, displays become more smoother, dark streaks solve the shooting screen.

              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:

              ● 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 2427 components, to form a complete control of pixel, color mixing uniformity and consistency;

              ● Single-wire synchronous control, built-in one-way transmission function, the concatenation shaped output; prevent attenuation data;

              ●OUTR/G/B each 4bits current gain adjustment bit, grayscale adjustment circuit ((gamma correction) 65536 gray scale adjustable);

              ● Current driver as high-accuracy and high stability oscillator, current error <± 5%.

              ● Built-in PWM patented technology, refresh rate up to 4KHz, signal transmission rate of 800Kbps.

              ● When sending current gain data, all need to send 16bits current gain adjustment bit. When sending RGB three-color current gain bits, the reserved 4bits gain data is also randomly input, but it can not be null; any data can be sent.
