Power Reference Designs

Download...and you're done.

Our power supply reference designs are proven circuits built to support common application parameters. Each design has been built and performance tested and comes with comprehensive, standardized documentation, including:

  • Detailed design note
  • Verification test results
  • Schematic
  • Bill of materials
  • PCB artwork

Download the file set to use as-is—and you’re done! Or tweak the design to fit your specific needs. Either way, you’ll significantly reduce development risks while accelerating time-to-market for your designs.
