Note that Cell A109 in the calculator tool for designing a positive-negative split-rail power supply is mislabled. It says "Copos" but should in fact say "Max Co ESR"
Part Number: TPS54140 Tool/software: Hi team,
Our customer want to AC analysis by TPS54140 PSpice Average Model to Split-Rail topology.
They want to check Bode plot on setting value of result of calculate tools(SWIFTPOSNEG-CALC-v4).
Is it possible…
Part Number: TPS54560 Other Parts Discussed in Thread: TPS54360 I've designed a circuit referring to the document SLVA369A using TPS54560, it has 24V input and ±15V output. but when I turn the input 24V on, nothing happened. I've compared my design to…
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…
Part Number: LMR16030 Other Parts Discussed in Thread: SWIFTPOSNEG-CALC , TPS54160 Dear Sir
I saw TPS540x0 have negative calculator
May I know LMR160x0 have the similar calculator for dual output ?
Thanks
Gary,
You cold consider a single TPS54160A solution as shown in this split rail, dual +/- design:

There are different output current versions depending on your need. There is a design calculator available here:

Richard,
The principle is the same for all the TPS54X60 and TPS54X40 devices. The GND nodes you highlight in red are the TPS54360B ground which is "VONEG", the negative output voltage (VONEG=IC ground). The "GND" highlighted in yellow is the system…
Hello Watanbe,
Thre is also spreadsheet that could be used to calculate parameters for split power supply.
Here is link

Hi Ammar,
We have a TI Precision Design that should provide a good starting point. You can find it here:
You will need to make some minor adjustments for zero and full-scale adjustment. For the full scale adjustment, you can just make the gain setting…
