What the SM16703P family does
The SM16703P is a single-wire transmission, three-channel LED driver control IC designed for decorative lighting. It features a 5 to 24 V input voltage range, 26 V output port withstand voltage, and a default constant current of 17 mA. The device supports 256-level brightness adjustment and operates at an 800 Kbps data transmission rate. Typically used for indoor LED decorative lighting, architectural facade illumination, and curtain screens, this chip integrates a constant current circuit and SPWM output drive technology to manage red, green, and blue channels efficiently.
