ISL97672B规格书详情
6-Channel LED Driver with Ultra Low Dimming Capability
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.
