ISL97672BIRZ - Renesas Electronics
Description: 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
