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": 12,
  "out": 12,
  "i": 1
}

Accuracy and scope

Ideal CCM inverting topology; excludes ripple peaks and ringing. Simplified analytical model; not a design recommendation or safety certification.
