Do we have unencrypted spice model for this IC so that we can tryout in LTspice. I have tried using ORCAD pspice basic setup is working.
I have tried to remove the ideal capacitors and replace them with actual model along with board parasitic and i found the response is not consistent. The voltage either shootup to KV range or ringing with frequency equal to LC after the board model will be present. The board model is extracted using Ansys SI wave tool.
extracted model from SI wave is simulated for transient pulse in LTspice and it is satisfactory
Thats the reason i have been looking for buck equivalent circuit model in my earlier post which would solve this problem to certain extent
