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
