ISL97673 Description
The ISL97673 drives 6 channels of LED to support 78 LEDs from 4.5V to 26V or 48 LEDs from a boost supply of 2.7V to 26V and a separate 5V bias on the ISL97673 VIN pin. The ISL97673 pensates for non-uniformity of the forward voltage drops in the LED strings with its six voltage controlled-current source channels. Its headroom control monitors the highest LED forward voltage string for output regulation, to minimize...
