Key Document


This automotive sepic converter reference design provides 11.0V @ 0.3A from an input voltage range of 4V to 13V. The sepic topology allows the input to vary below and above the regulated output voltage. A free-running switching frequency of 400KHz enables small circuit size with good efficiency. Power stage components operate below 41 degrees Celsius.

  • Compact size
  • Low EMI
  • Automotive qualitifed controller TPS55340-Q1
  • Test report and design files available
