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.

Key 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 of PWM and DC current adjustments. The SMBus PWM dimming frequency can be adjusted from 100Hz to 5kHz by an.
