Texas Instruments LM3552SDEV

LM3552 Evaluation Board

Product Technical Specifications

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.
  • Dev Kit Description

    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.)

  • Dev Kit Features

    • Up to 1A total drive current
    • Flash timeout protection
    • Independent Torch/Flash/Shutdown modes
    • LED disconnect in shutdown
    • Programmable soft-start limits inrush current
    • Over-voltage protection
    • Wide voltage range 2.7 to 5.5V
    • 1.25MHz constant switching frequency
