ISL97672 6-Channel LED Driver OBSOLETE PRODUCT RECOMMENDED REPLACEMENT PARTS ISL97671A or ISL97672B DATASHEET FN7632 Rev.4.00 Sep 8, 2017 The ISL97672 is an integrated power LED driver that controls 6 channels of LED current for LCD backlight applications. The ISL97672 is capable of driving up to 78 LEDs from 4.5V to 26V or 48 LEDs from a boost supply of 2.7V to 26V and a separate 5V bias supply on the VIN pin. The ISL97672 compensates for non-uniformity of the forward voltage drops in the LED strings with its 6 voltage controlled-current source channels. Its headroom control monitors the highest LED forward voltage string for output regulation, to minimize the voltage headroom and power loss in a typical multi-string operation. The ISL97672 allows direct PWM mode by following the external signal from 0Hz to 30KHz at 0.4% to 100% duty cycle and maintaining a typical ±0.7% current matching between channels. The ISL97672 features a separate EN pin and extensive protection functions t...
