Description

Electronic Component Model:ISL97672BIRZ LED Drivers 6-Channel LED Driver with Ultra Low Dimming Capability. The ISL97672BIRZ is an integrated power LED driver that controls six channels of LED current for LCD backlight applications. It can drive LEDs from 4.5V to 26.5V, with a maximum output of 45V. The ISL97672BIRZ employs an adaptive boost switching architecture that allows direct PWM dimming with linearity as low as 0.007% at 200Hz or 0.8% at 20kHz. Dimming can be as high as 30kHz.
