ISL97687
4-Channel LED Driver with Phase Shift Control and 10-Bit Dimming Resolution
FN7714 Rev.4.00 Jun 7, 2019
The ISL97687 is a PWM controlled LED driver that supports four 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. This adaptive scheme compensates for the non-uniformity of forward voltage variance in the LED strings.
The ISL97687 can decode both an incoming PWM signal and an analog input voltage, for DC-to-PWM dimming applications.
