ISL97675 NOT RECOMMENDED FOR NEW DESIGNS RECOMMENDED REPLACEMENT PARTS ISL97671A or ISL97672B 4-Channel LED Driver with Phase Shift Control DATASHEET FN7630 Rev.2.00 Sep 13, 2017 The ISL97675 is an LED driver that drives 4 channels of low power LEDs from 4.5V to 26V input and up to 45V output. The ISL97675 compensates for non-uniformity of the forward voltage drops in the LED strings with its 4 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 the typical multi-string operation. The ISL97675 offers two PWM Dimming modes: The part digitizes the incoming 100Hz to 30kHz PWM signal and provides 8-bit PWM dimming with phase shift function.
