AL3644 Datasheet (Diodes) - DUAL 1.5A CURRENT SOURCE CAMERA FLASH LED DRIVER

AL3644, DUAL 1.5A CURRENT SOURCE CAMERA FLASH LED DRIVER

The AL3644 is a dual LED flash driver that provides a high level of adjustability within a small solution size.

The AL3644 utilizes a 2MHz or 4MHz fixed frequency synchronous boost converter to provide power to the dual 1.5A constant current LED sources.

The dual 128 level current sources provide th

AL3644 Features

* of the AL3644 are controlled via an I2C-compatible interface. These features include: hardware flash and hardware torch pins (STROBE and TORCH/TEMP), a TX interrupt, and an NTC thermistor monitor. The device offers independently programmable currents in each output leg to drive the LEDs in a Flash o
