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. The AW36518 provides IVFM protection to prevent system reset or shutdown under low battery condition. The AW36518 are controlled via an I2C compatible interface. The main features of the AW36518 include: flash/torch current, flash timeout duration, IVFM and TX interrupt. The AW36518 also provides hardware flash/torch pin (STROBE/TORCH) to control Flash/Torch events. The 2MHz or 4MHz switching frequency options, overvoltage protection (OVP), and adjustable current limit ...
