4-Channel LED Driver with Phase Shift Control and 10-Bit Dimming Resolution ISL97687 The ISL97687 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 ISL97687’s current sources achieve typical current matching to ±1%, while dynamically maintaining the minimum required VOUT necessary for regulation.
