ISL97636A Datasheet | Renesas

6-Channel LED Driver The ISL97636A is an integrated power LED driver that controls 6 channels of LED current for LCD backlight applications. The ISL97636A is capable of driving typically 54 (6x9) pieces of 3.5V/30mA or 60 (6x10) pieces of 3.2V/20mA LEDs. The ISL97636A’s contains 6 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 ISL97636A Features a dynamic headroom control that monitors the highest LED forward voltage string and uses its feedback signal for...
