TPS61322: WEBENCH not able to provide a design

Part Number: TPS61322

Hello,

when trying to use the TI WEBENCH for the part TPS613226A with the following input data, I always get an error message that the design cannot be created even though I'm totally within the device limits.

Kind regards,

Markus Schyma

  • Hi Markus,

    Thanks for selecting our device. I either cannot create a design based on your condition. I have forwarded the question to Webench team and I expect to have answer in this week.

    An alternative way for your design is to refer to datasheet 9.2.1.2 or TI EVM or create the design based on WEBENCH default setting. 

    Please also note the 0.3A IOUT is exceeding datasheet current limit specification. The design with 1.5V minimum VIN, 3.6VOUT and 0.3A IOUT will need at least 0.8A current limit. TPS613226A's minimum current limit spec is 0.75A, which cannot meet your needs.

  • Dear Wenhao,

    thank you.

    Seems the TPS613221A is able to do it (with 3.3V output voltage), but I cannot simulate the design in WEBENCH....

    "simulation not enabled for this design".

    Best regards,

    Markus

  • Hi Markus,

    I have required WEBENCH team to check the simulation for us. I am still waiting for their feedbacks about timeline. It may take some time before it can work on web.

    If you are urgent with the design, could you please refer to datasheet for specific design reference? Thank you very much!
