Part Number: TPS63710

Dear Team,

Here is Kevin from Delta Taiwan team.

Customer have 12Vin would like to have -12V/1.5A output.

Do we have more suitable device here?

    Hi Kevin,

    What is the range of input voltage? Can you also provide more requirements like efficiency or footprint or any specific features you are looking for? Also, are you open to using a buck converter in an inverting buck-boost configuration (depends on Vin range that you specify)?  

    Regards,

    Amod

    Dear Amod,

    Thanks for the input. You can list down the solution you have, I can double check with the engineer.

    What is the range of input voltage?  12V+-5%

    Can you also provide more requirements like efficiency or footprint or any specific features you are looking for?  

    As simple as possible with lowest part count is appreciated

    Also, are you open to using a buck converter in an inverting buck-boost configuration (depends on Vin range that you specify)?   Customer had try it before, but it seems no such all in one IC can support up to 1.5A.

    BR

    TPS63710 is a good option but supports 1A at output. Other options like a buck to IBB but then will need level shifters as an example and that will increase part count. I did not see a tested working 12V-> -12V at 1.5A in reference designs except the https://www.ti.com/tool/PMP4369 Hope this helps.

    Regards,
