RGB WS2812 Introduction
The WS2812 RGB LED lamp is a three-channel drive control. It contains an intelligent digital interface
data latch signal shaping and amplifying driver circuit. It also includes a high-precision internal oscillator
and a 15V high-voltage programmable constant current output driver. At the same time, in order to reduce
the power supply ripple, the three channels have a certain delay turn-on function, which can reduce the
circuit ripple installation more easily during frame refresh.
Unlike the traditional RGB LED lamps, the WS2812 RGB LED lamps integrate a dedicated driver control
chip to control one LED bead or multiple LED modules with a single signal line. Its main features are as
follows:
⚫ Output port withstand voltage 15V
⚫ Built-in voltage regulator tube, only 24V power supply terminal only needs string resistor to IC
VDD pin, no need to add regulator tube
⚫ Grayscale adjustment circuit (256 levels of grayscale adjustable)
