Part Number: TPS54623
Other Parts Discussed in Thread: TINA-TI,

Tool/software: TINA-TI or Spice Models

Hello,

I used TI webench tool to design a circuit for 12V input 5V 5A output with TPS54623, but the webench circuit cannot get the correct voltage output with Tina simulation. See the attachments, anything wrong? Thanks.

    Hi,

    Kindly do not put extra effort in designing the TINA-TI schematic as per WEBENCH design. This may cause some mistake during designing. 

    We have TINA-TI export available in WEBENCH designer tool. Kindly follow the below steps to get exported WEBENCH design in TINA-TI.

    1. Provide input/output conditions and click on Open Design.

    2. A new window will open. Click on EXPORT on right top corner. Then choose TINA-TI and finally click on EXPORT DESIGN.

    3. When the export is completed, you will be notified to download the TINA-TI .TSC file. Please download it and simulate.

    Kindly let us know if you face any issue/mismatch in simulation result.

    Thanks & Regards,
