Applications
High Current Applications
Each channel of the ISL97675 can support up to 40mA.
For applications that need higher current, multiple
channels can be grouped to achieve the desirable
current. For example, the cathode of the last LED can be
connected to FB1 to FB2, this configuration can be
treated as a single string with 80mA current driving
capability.
