AW36518 Overview
The AW36518 is a LED flash driver that provides a high level of adjustability within a small solution size. The AW36518 utilizes a 2MHz or 4MHz fixed-frequency synchronous boost converter to provide power to the 1.5A constant current LED sources. The 256 levels current sources provide the flexibility to adjust the current of LED in Flash/Torch/IR modes.
