DATASHEET ISL97672B 6-Channel LED Driver with Ultra Low Dimming Capability FN7995 Rev.3.00 Sep 7, 2017 The ISL97672B is an integrated 6-channel power LED driver for LCD backlight applications. The ISL97672B is capable of driving LEDs with an input from 4.5V to 26.5V and a maximum output up to 45V. The ISL97672B employs an adaptive boost switching architecture that allows direct PWM dimming with dimming duty cycle as low as 0.007% at 200Hz or 0.8% at 20kHz. PWM Dimming frequency can be as high as 30kHz. The ISL97672B employs dynamic headroom control that monitors the highest LED forward voltage string for output regulation to minimize headroom voltage and power loss in a typical multi-string operation. Typical current matching between channels is ±0.7%.
