Hi all,

I have the following syntax error when I try to run the simulation: "Unknown symbol: ss".

Anyone of you know how it can be possible to fix it?

Thx in advanced.

Hi Francesco,

We are not allowed to support LTSpice simulation due to their EULA.

The Unencrypted PSpice model for the LMR14050 in the product folder is unencrypted and should function properly in a simulator that supports PSpice model import with following modification in subcircuit definition:

.SUBCKT LMR14050S_TRANS BOOT VIN EN RT_SYNC FB SS GND SW PAD PARAMS: SS=1

Thanks!!

Best Regards,
