DATASHEET ISL97686 4-Channel LED Driver with Independent Channel Control for Dynamic Dimming FN7953 Rev.1.00 Sep 19, 2017 The ISL97686 is a PWM controlled LED driver that supports 4 channels of LED current for monitor and TV LCD backlight applications. It is capable of driving 160mA per channel from a 9V to 32V input supply, with current sources rated up to 75V absolute maximum. The ISL97686’s current sources achieve typical current matching to ±1%, while dynamically maintaining the minimum required VOUT necessary for regulation. This adaptive scheme compensates for the non-uniformity of forward voltage variance in the LED strings.
