SM16206S

SM16206 is a constant-current LED driver IC with built-in CMOS shift register and latch functionality, capable of converting serial input data to parallel output data format. The SM16206 operates at 3.3V–5.0V and provides 16 current sources, delivering a constant current of 1mA–32mA per output channel. Current mismatch between channels within a single IC is less than ±2.5%; current mismatch between multiple ICs is less than ±3.5%. Output current remains stable regardless of output voltage variations (<VDS); current variation due to supply voltage and ambient temperature is less than 1%. The output current of each channel is adjustable via an external resistor. The SM16206 output ports support a maximum voltage of +15V, allowing multiple LEDs to be connected in series on each output. In addition, the SM16206 supports clock frequencies up to 25MHz to meet system requirements for high-volume data transmission.
