12CH with Auto-Breathing

The ET6312B are four constant current RGB LED drivers with I2C interface. The devices are ideally powered from 3.3V or 5V supplies. The independent programmable constant current sinks operate without external components.By the nine internal registers programming, the each three LED channels can work • Ultra low dropout regulated current sinks, 75mV typical at 10mA per channel\n\n• Each nine programmable LED setting registers are shared by each three LED\n\n• I2C control, one ADDR pin realize four chip address selection\n\n• SYN pin can supply chips cascade synchronous clock\n\n• EXPWM pin for e;
