How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "vin": 6,
  "out": 12,
  "l": 0.0001,
  "f": 100000,
  "i": 1
}

Accuracy and scope

Ideal CCM model; excludes converter efficiency and diode losses. Simplified analytical model; not a design recommendation or safety certification.
