WS2818B LED Driver Board, 5V, Dual-signal Transmission, 100 Pack

WS2818B is 3 output channels special for LED driver circuit. Its internal includes intelligent digital port datalatchand signal reshaping amplification drive circuit. Also include a precision internal oscillator and a 20Vvoltageprogrammable constant current output drive.It effectively ensures that the color of the pixel point light onthedrivingcircuit is highly consistent. IC use single NZR communication mode. After the chip power-on reset, the DIN1 port receive data fromcontroller,the first IC collect initial 24bit data then sent to the internal data latch, the other data which reshaping bytheinternalsignal reshaping amplification circuit sent to the next cascade IC through the DO port. After transmission for eachchip,the signal to reduce 24bit. IC adopt auto reshaping transmit technology, making the chip cascade number is not limitedthe signal transmission, only depend on the speed of signal transmission. The data latch of IC depend on the received 24bit data produce different duty ratio signal at OUTR, OUTG, OUTBport. All chip synchronous send the received data to each segment when the DIN1 port input a reset signal. It will receivenew data again After the reset signal finished. Before a new reset signal received, the control signal of OUTR,OUTG,OUTB port unchanged. IC sent PWM data that received justly to OUTR, OUTG, OUTB port, after receive a lowvoltagereset signal the time retain over 280μs
