Reference Design: Programmable, 3-Channel LED Current Source Driver with isoSPI Repeater

CN0410 is a 3-channel, programmable, LED current driver with digital communications repeater capabilities. Each of the three output channels is controlled by a single DAC, which simplifies the digital communications and reduces cost. Each channel can be individually programmed and is capable of sourcing 1 A of current through its load. The circuit also has an isoSPI™ repeater that allows multiple boards to be controlled with a single master. The repeater translates the serial port interface (SPI) signals into pulses that are transmitted through a twisted pair of wire and converted back to an SPI signal at the other end.
