Overview
   TC26703 is a single-line transmission three-channel LED driver control chip that uses a unipolar return-to-zero code communication protocol. The chip contains a power supply voltage regulator circuit, a signal decoding module, a data buffer, a built-in constant current circuit, and the output drive uses patented SPWM technology, as well as a built-in RC oscillator.
