AL3644 Camera Flash LED Drivers

Diodes Incorporated AL3644 Camera Flash LED Drivers are dual LED flash drivers that provide a high level of adjustability within a small solution size. These Diodes Incorporated drivers utilize a 2MHz or 4MHz fixed-frequency synchronous boost converter to power the dual 1.5A constant current LED sources. These current sources also offer the flexibility to adjust the current ratios between LED1 and LED2. The AL3644 LED drivers feature a hardware torch, flash pins (TORCH/TEMP and STROBE), an NTC thermistor monitor, and a TX interrupt. These LED drivers offer independently programmable currents in each output leg to drive the LEDs in flash or movie mode (torch) conditions. The AL3644 LED drivers are RoHS compliant and operate over -40°C to 85°C. These LED drivers are ideal for camera phones with white LED flash.
