Overview
ISL97636 8-Channel LED Driver The ISL97636 is an integrated power LED driver that controls 8 channels of LED current for LCD backlight applications.
The ISL97636 is capable of driving typically 72 (8x9) pieces of 3.
5V/30mA or 80 (8x10) pieces of 3.
2V/20mA LEDs.
The ISL97636’s contains 8 channels of voltage controlled current sources with typical currents matching of ±1%, which compensate for the non-uniformity effect of forward voltages variance in the LED stacks.
To minimize the voltage headroom and power loss in the typical multi-strings operation, the ISL97636 features a dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for output ...
