Hi Team,

I’ve got a crash when running TPS54561-Q1 simulation with PSpice for TI. But try other chipsets (I try LM25117) was fine. Could the TPS54561-Q1 to be applied crash issue?

Thank you.

Hi Roy,

Thanks for your patience, have you had any issues with the PSPICE transient model? The team is moving away from the TINA models and so they are not compatible and might be causing the crash. Let me know if you have further issues.

Regards,

Henry
