Hi Jeno,
I have few comments.
1. If you need EN connection, recommend you to refer snva856b app note section 7.1.
2. The compensation values are incorrect. I think the values for snubbers are just copied for compensation values as well. Depending upon…
Hi,
Regarding components and values: i would suggest you to refer https://www.ti.com/product/TPS54360B#design-tools-simulation / https://www.ti.com/tool/download/SWIFTINV-CALC / https://www.ti.com/tool/download/SLVC452 excel tool based on input, output voltage…
Part Number: TPS54340 Other Parts Discussed in Thread: LMR14050 I am using the Swift inverse Calculator spreadsheet from the TI website (SWIFTINV-CALC-REVE) to create buck-boost-inverting circuits.
It’s super helpful, but I don’t know what these extra…
Carlo,
Looking at the product folder for TPS54060 there are a couple of quickstart calculators there.
The publication was most likely renamed.
I would refer them to https://www.ti.com/tool/SWIFTINV-CALC
There also this calculator but probably not applicable…
Hi,
After researching, maybe this would help?

Another way is to use an EVM and modify the components for inverting configuration
Thanks

Tetsuro,
Another possibility is TPS54240 or TPS54260 (if you need more input voltage margin). There is an app note here:
www.ti.com/.../slva317b.pdf
The app note is suitable for any device in that product family. There is also a design calculator here…
User,
TPS54560B l\looks like a good match for your inverting buck-boost:
www.ti.com/.../TPS54560B
You can use this app note which works for TPS54560B as well:
www.ti.com/.../slva317
There is an excel calculator available that should make your design…
Nishazawa-san,
I would probably start here: www.ti.com/.../description
There are technical resources here: www.ti.com/.../slva317 , www.ti.com/.../slva540
And design tool here: www.ti.com/.../swiftinv-calc
Then that series of devices should work well. Since the current peak current is greater than the load current by a factor of 1-D you may need TPS54140A Rather than TPS54040A.
There is a calculator here:
www.ti.com/.../swiftinv-calc
We (TI) may have…
Yes you can do that. Here are some app notes that explains it. It is applicable to TPS54531:
www.ti.com/.../slva540
www.ti.com/.../slva317
And a calculator tool:
