The AW3648 is a LED flash driver that provides a high level of adjustability within a small solution size. The AW3648 utilizes a 2MHz in 4MHz fixed-frequency synchronous boost converter to provide power to the 1.5A constant current LED sources. The 64 levels current source provides the flexibility to adjust the current of LED in Flash/Torch/IR modes. The AW3648 provides three IVFM protection modes to prevent system reset in shutdown under low battery condition.
The AW3648 is controlled via an I2C-compatible interface. The main features of the AW3648 include: flash/torch current, flash timeout duration, IVFM, TX interrupt, and NTC thermistor monitor. The AW3648 also provides hardware flash and hardware torch pins (STROBE and TORCH/TEMP) to control Flash/Torch events.
The 2MHz in 4MHz switching frequency options, overvoltage protection (OVP), and adjustable current limit allow for the use of tiny, low-profile inductors and 10-µF ceramic capacitors. The device operates over a –40°C to +85°C ambient temperature range.
The AW3648 is available in small 0.4mm pitch 1.626mm×1.332mm CSP-12 package.
