Overview
ISL97635A SMBus 6-Channel LED Driver The ISL97635A is a digitally controlled LED driver that controls 6 channels of LED current for LCD backlight applications.
The ISL97635A is capable of driving typically 54 (6x9) pieces of 3.
5V/30mA or 60 (6x10) pieces of 3.
2V/20mA LEDs.
The ISL97635A contains 6 channels of voltage controlled current sources with typical currents matching of ±1%, which compensate for the non-uniformity effect of forward voltages variance in the LED stacks.
To minimize the voltage headroom and power loss in the typical multi-strings operation, the ISL97635A features a dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal ...
