    Hello Suma, 

    Thank you very much for reaching out. 

    TPSI3052-Q1 is a new and innovating solution in which driver and supply are integrated within the same device. I do not believe we have an alternate part for TPSI3052-Q1 at the moment.

    Out of curiosity, I was wondering if there is a specific reason why you are trying to find an alternate part for the TPSI3052-Q1? Is the device missing some features that your design requires ? Are some of the specifications in your system different from the ones the device offers? 

    Sincerely, 

    Francisco Lauzurique

    Hi Suma,

    It is a pleasure to meet you and welcome to the E2E forums Slight smile

    The TPSI3052-Q1 is finishing the release-to-market process and will start to become available with production supply next week. Order entry will become open for purchase orders (POs) either directly or through distributors in standard/minimum quantities (1ku) for TPSI3052QDWZRQ1.

    Lower volume samples or purchases will become available on TI.com though quantities and availability may vary. Please subscribe to the product folder to get notified of any changes.

    In the meantime, I believe some samples are available of the industrial grade version, TPSI3052, which will behave the same for evaluation purposes.

    We also have a footprint compatible device with lower gate voltage output (10V), TPSI3050-Q1 here:

    Hello Suma, 

    Thank you very much for reaching out.

    There are a few issues that could be happening here, but I am not sure what is this source of this error in your side. I downloaded the files and I was able to simulate the device without issues. I will share general best practices to help you debug this issue. 

    1- Place a large value resistor between the primary ground and the secondary side. Sometimes you can observe convergence issue when having floating grounds. 

    2- Use Initial Conditions (IC) when having floating nodes between capacitors.

    3- Use auto-convergence settings. 

    4- Ensure you have included the library location for the TPSI3052-Q1

    Schematics and Waveforms included

    Let us know if this answers all your questions. 

    Sincerely 

    Francisco Lauzurique

    Hi Francisco,

    Thank you for guiding in pspice. Kindly, suggest alternate part for TPSI3052-Q1 so that will be helpful. And if your find the similar function component that will helpful i want to run the simulation in PSIM as per customer requirement for this part it is through error. Solve this error we will continue with this part. The error it is showing is 

    AND2 is not present in the subcircuit.

    Thank you,

    Suma

    Is this error showing in PSPICE For TI? Can you please share your circuit so I can try to recreate it.

    Hi Tilden

    Is this error showing in PSPICE For TI? Can you please share your circuit so I can try to recreate it.

    I am getting this error in Lt-spice. As per the customer requirement they need simulation result in PowerSIM. Kindly, help me solve this issue. This is what i getting error.

     

    Thank You,

    Hello Suma,

    TI does not support simulation in LTSpice. These models have been created for and verified with PSpice for TI:

    The following zipped project works for me. e2e-suma-3052.zip

    Make sure you're referencing the following library for TPSI3052-Q1. slvmdv1b.zip

    Hello Suma,

    I was able to recreate the errors when I opened your file here:

    Removing the nom_pspti.lib file from the simulation settings fixed that error and I was able to simulate the circuit.
