WEBENCH® Tools/TPS65130: Query

Rudra Prakash
Intellectual 370 points
Part Number: TPS65130
Other Parts Discussed in Thread: TINA-TI, TPS65133

Tool/software: WEBENCH® Design Tools

Hello,

I want to design TPS65130 for +9V and -9V output, but Webench design is not supporting Negative/inverting output, -9V. Could you please tell me the reason why webench design of TPS65130 is not supporting the Negative/Inverting Output? Is there any other method on WEBENCH to check both positive and inverting voltage output at the same time? 

Please provide a solution to check response at both the output of TPS65130.

Thanks & Regards,

Rudra Prakash

    Hello Rudra,

    This device does not have a full web bench model available but datasheet has enough information to design for both boost and inverting buck-boost converters. Please let me know if there are any questions after you have reviewed the information in the datasheet.

    Kind Regards,

    Hello Liaqat,

    Is there any TINA-TI or Pspice model available for this part?

    If not then can you please tell me which is the closest part I can use for the simulation?

    Thanks & Regards,

    Hello Rudra,

    I searched through the split rail converters (+/- supplies from a single positive input supply) similar to TPS65130/31 but unfortunately did not find a device with similar specs. The closest is TPS65133 but that also does not have web-bench or TINA models available.

    If you have any specific questions about calculating a component value or a parameter, please let me know and I will be glad to look into it and try to answer your questions.

    Kind Regards,

    Liaqat
