Original question:

TPSI3050: Simulation failure

TPSI3050: found TPSI3050 in PSpice for TI but get error

Hans

Part Number: TPSI3050

Hello team,

I get this error when using the device:

ERROR(ORPSIM-15108): Subcircuit TPSI3050 used by X_U1 is undefined

May I kindly ask for an explanation, please? If I find a TI part it should work and be in the library, right?

Thank you and Best Regards, Hans

    Hello Hans,

    I noticed you have emailed our team after creating this post, I've responded there and am closing this thread. If you can please update us here with the workaround you found for this error, that may be helpful for future reference (guessing it was adding the TPSI305x.lib file to Configured Files in Simulation Settings).

    Best regards,

    Hi Tilden,

    I simulated TPS3052 by removing nom_pspti.lib from the configured library files and added 2 FETs (power_nmos_p). Please find PSpice for TI project, schematics and simulation results attached.
