ISL97635 - SMBus 8-Channel LED Driver

ISL97635 Description

ISL97635 SMBus 8-Channel LED Driver The ISL97635 is a digitally controlled LED driver that controls 8 channels of LED current for LCD backlight applic.

ISL97635 Features

* a dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for output regulation. The LED dimming control can be achieved through a SMBus, an external PWM, or a variable DC (analog light sensor) input. SMBus controlled dimming allows 256 levels each

ISL97635 Applications

* The ISL97635 is capable of driving typically 72 (8x9) pieces of 3.5V/30mA or 80 (8x10) pieces of 3.2V/20mA LEDs. The ISL97635’s 8 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
