The synchronous concept is beneficial for driving high power LEDs with maximum system efficiency or to provide a high power constant voltage supply for lighting and non-lighting application. To give maximum flexibility for different applications both DC-DC channels of the TLD5501-2QV can be operated separately or in multiphase.

Features

  • Dual-chan.synchronous Buck DC-DC
  • Constant Current & Constant V Regulation
  • Individual chan. or Multiphase operation
  • Wide VIN R
  • Wide LED forward V R (2V to 50V)
  • LED accuracy+/-3% at Tj=25° & 5% temp R
  • 16bit SPI for diagnostics & control
  • >Efficiency in every condition up to 96%
  • Limp Home Function (Fail Safe Mode)
  • Flexible current sense
  • EMC optimized device
