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…
Part Number: TPS54540 Hi TI
We use TPS54540 in an inverting buck configuartion. We have automated test systems that analyse the switching waveform of the DCDC converters, for verifying proper function. But on one out of 50 units, our inverting buck…
Part Number: TPS54160A Other Parts Discussed in Thread: TPS54160 ,
Tool/software:
Hi, I'm using the TPS54160ADRCR as an inverting pwr supply, from +24V to -6V following the SWIFTINV-CALC-REVE.xls excel sheet and the SLVA317B document instructions…
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…
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…
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…
Hi,
After researching, maybe this would help?

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

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…
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
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…
