Our built-in IC RGB LED compatible all the IC leds which you had see in market, such as WS2812 WS2818B WS2811 SK6812 6803 etc, and compatible all the controller, you can choose use or not use the capacitane,Breakpoint resume,inside has two-line controll,more detail pls contact us

HY-5050IC4RGB-N5302 is a external controlled constant current 5050 integrated LED that integrates a high-quality single-line cascaded constant current driver IC N5302 and a high-quality RGB LED chip. The built-in control IC N5302 has the characteristics of high reliability, low power consumption, high anti-interference performance and high constant current accuracy, while the internal integration is preferable to high-quality LED chips, with excellent luminous uniformity, pure white light, and low light attenuation. HY-5050IC4RGB-N5302 will combine the advantages of the two, while bringing small size, fewer external components, layout clean features. Controlled by an external controller to show magic, animation, and high-standard video effects

Built-in LED parameters

HY-5050IC4RGB-N5302 LED use single-line communication, using reset code to send signals. After power-on reset, the chip accepts data from the DIN terminal. After receiving 24 bits, the DO port starts to forward data for the next chip to provide input data. Before forwarding, the DO port stays low. At this time, the led chip will not accept new data. The built-in RGB chip displays different brightness according to the different duty cycle signals generated after the received 24 bit data. The refresh cycle is about 0.6 ms . If the DIN input signal is reset signal, the chip will send the received data display, the chip will receive new data after the end of the signal, after receiving the start of the 24bit data, forward the data through the DO port, the lamp beads in the Before receiving the reset code, the RGB brightness remains unchanged. After receiving a Vil input reset code of 24 μs or more, the internal RGB chip of the lamp will display different brightness according to the different duty ratio signals generated by the 24 bit data just received
