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.
Another mode is direct PWM mode without phase shift, where the dimming frequency follows the input PWM signal and the minimum on time can be as short as 350ns.
The ISL97675 features channel phase shift control to min...
