ISL97635规格书详情
The ISL97635 is a digitally controlled LED driver that controls 8 channels of LED current for LCD backlight applications. The ISL97635 is capable of driving typically 72 (8x9) pieces of 3.5V/30mA or 80 (8x10) pieces of
3.2V/20mA LEDs. The ISL97635’s 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 ISL97635 features a dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for output regulation.
