LM43601: Cannot reproduce Webench simulation on LT-SPICE24

Nicolas J.

Part Number: LM43601


Hello,

The LT-SPICE 24 simulations of the LM43601 configured to output neg12V from a pos15V input failed so far. 

I am using the following LM43601_AVG.LIB model which I believe is correct.

The schematic is identical to the one proposed on Webench.

Any idea on what could explain the simulation failures?

Thanks!

    Hello Nicolas,

    Unfortunately due to the licensing agreement on LT SPICE, ADI is the only semiconductor manufacture that can provide models or use LT SPICE.  In some cases importing information from the unencrypted model works well, but not always.  We cannot troubleshoot any issues.  Sorry about this, I wish we could provide more support in this regard.
