ISL97687 4-Channel LED Driver

Renesas Electronics ISL97687 4-Channel LED Driver supports four LED current channels for monitor and TV LCD backlight applications. The SL97687 uses a 9V to 32V input supply, capable of driving 160mA per channel with current sources rated up to 75V absolute maximum. Typical current matching to ±1% is achieved via the ISL97687’s current sources. Meanwhile, the device is 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.
