AW3642

AW3642 Oct 2018 V1.4 High Efficiency, 1.5A Flash LED Driver FEATURES GENERAL DESCRIPTION  1.5A Accurate and Programmable LED Current Source The AW3642 is a LED flash driver that provides a  Flash:23.4mA~1.5A，64 levels 23.44mA/level high level of adjustability within a small solution size. The AW3642 utilizes a 2MHz or 4MHz fixed-frequency synchronous boost converter to l  Torch:5.4mA~376mA，64 levels 5.88mA/level  Flash Timeout：40ms~1.6s，16 levels  Flash/Torch/IR Mode  High Efficiency: 85% tia 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 AW3642 provides three IVFM protection modes to prevent system reset or shutdown under low battery condition.  Optimized Flash LED Current During Low Battery Conditions (IVFM) n The AW3642 is controlled via an I2C-compatible interface. The main features of the AW3642  Hardware Strobe Enable (STROBE)  Synchronization Input for RF Power Amplifier Pulse Events (TX)  400kHz I2C:AW3642（I2C Address=0x63）  0.5mm Pitch, CSP-9 Package APPLICATION include: flash/torch current, flash timeout duration, IVFM, TX interrupt. The AW3642 also provides e hardware flash pins (STROBE) to control flash events. d The 2MHz or 4MHz switching frequency options, i overvoltage protection (OVP), and adjustable f current limit allow for the use of tiny, low-profile Smartphone Camera Flash ninductors and 10-µF ceramic capacito...
