High Voltage Ratio Vout/Vin, 2W Boost Converter Reference Design


Design files


When high voltage ratio between output and input is required, it's always difficult to choose the right topology. In this case, the most-simple Boost has been selected due to cost reasons. The converter runs in DCM mode therefore avoiding the Trr of the diode and shows good efficiency.

  • Good efficiency values despite the high Vout/Vin ratio
  • Simple and low cost solution
