ISL97672A NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PART ISL97672B 6-Channel LED Driver with Ultra Low Dimming Capability DATASHEET FN7710 Rev.4.00 Sep 14, 2017 The ISL97672A is an integrated 6-channel power LED driver for LCD backlight applications. The ISL97672A is capable of driving LEDs with input from 4.5V to 26.5V and maximum output up to 45V. The ISL97672A 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 ISL97672A employs the 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.
