How does LPD6803 addressable led strip light work?
LPD6803 is a 3-channel constant current driver IC with internal serial shift registers and cascaded driver circuits, using advanced high-voltage CMOS technology to achieve 256-level grayscale adjustment and output 16 million dynamic color chasing effects, which suitable for industrial lighting.
The DIN/DCLK port of LED strip inputs the serial data output by the SPI LED controller, and the data is shifted into the serial shift register on the upper edge of the clock. After dumping, it is converted to 3-port parallel output by pulse width modulation, serial shift register and the gray-scale counter can be controlled by different clock signals. LPD6803 drives the data and control signals internally and then outputs them to the next-level circuit, the data clock signal passes through the built-in phase-locked regeneration circuit and is strongly driven to provide the next-level chip to improve the cascade level. number, the maximum current of a single channel is 45mA, supports DC12V input voltage.
