This LM3552SDEV power management development kit from Texas Instruments will help prevent unneeded energy consumption. Its output produces a current of 1000 mA. This part has single output. You can operate this at a switching frequency of 1250 KHz.
Description du kit de développement
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.)
