ISL97636 Datasheet | Renesas

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 pensate 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...
