The DiodesZetex makes 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 the flexibility to adjust the current ratios between LED1 and LED2. An adaptive regulation method ensures the current sources remain in regulation and maximizes efficiency.
Dual independent 1.5A LED current source programmability Accurate and Programmable LED current range from 1.4 mA to 1.5 A Optimized flash LED current during low battery conditions More than 85% efficiency in torch mode (at 100mA) and Flash mode (at 1A to 1.5A) Grounded cathode LED operation for improved thermal management
