LM3552SDEV: 700mA Photo Flash Driver

Summary

The LM3552 evaluation board provides an example of a high current white LED flash driver. Torch (continuous) mode and Flash (pulse) mode control is provided through a single dedicated control pin. On this evaluation board, the torch current is set to 200mA to allow continuous operation, whereas the flash current is limited to a one second, 700mA pulse.

Many flash specific safety features have been integrated into the LM3552 architecture and are utilized on the evaluation board design (Over-voltage protection, Flash Time-Out, Current Limit, etc.) For more information, please refer to the data sheet and applications note.
