Need something I can **** up to match a new DC-DC
converter that doesn't have mfr supplied models. I am
using LTSpice but can convert whatever I find. Most of
the bigger mfrs are encrypting their models so they are
not of any use to me. Either a LTSpice circuit w/ the guts,
or a plain text .subckt file would be ideal.
 

Dick,

It is a PITA the encrypted models. I have complained to numerous companies that using encrypted Hspice models, for example, limits their use to a small percentage of the designed in the world. Where possible I vote with my feet and use other companies devices.

Anyway, I don't know if it is of any help because it is a SMPS rather than a DC-DC, but there is a SMPS demo in the SIMetrix simulator called "flyback". If you cannot find it I can email it to you.

Keith.
