UTK Tiny Box Challenge 2020

A coursework competition to build a (very) small DC/DC converter

Full Competition Requirements


  • Deadlines
  • October 14th - Competition Begins
  • October 30th - Paper Design and Comparison Report Due
  • November 13nd - PCB Layout Due Must pass Manufacturer DFM/AFV check as detailed in competition requirements
  • December 9th - Testing Report Due
  • Example Testing Report
  • As discussed in lecture 25, you may opt to take a written final exam, rather than completing the experimental portion of the competition. If you choose to do so, requirements on the PCB layout are lessened, and no testing report is needed

  • What the Converter Needs to Do
  • The winning converter will be the one that achieves the highest power density and meeting a list of other specifications

    In brief, the other specifications are

  • Must operate up to 36W output power
  • Will take in 48Vdc
  • Must output 12 +/- 0.1 Vdc
  • Must achieve a power density greater than 10 W/in3
  • Must operate with no load with less than 2W of loss
  • Must achieve an efficiency greater than 95% (TPE Method)
  • Must have and output voltage ripple less than 1%
