Hi Jospeh,
Thanks for your inputs.
I have updated the power calculator and selected suitable Feedback and compensation network. Please review the schematics and power calculator bode plots and provide if any review comments. I would like to release…
Hello Tahar,
Below is the calculation tool file that the customer replied.

They said they couldn't change the values because they didn't understand the contents of the display items below. …
Hey Rajat,
You are correct, my mistake. I've fixed your calculator sheet. Your capacitance and bandwidth were too low to support your undershoot requirements. The excel sheet attached has component values that give a 6mV undershoot. You can double check…
Part Number: TPS544B25 Hi Team,
We are using TPS544B25 to generate the core rail of FPGA.
Can you please review the excel sheet of all voltage rail ?
Voltage and current requirment are in excel sheet name.

1/10 of the switching frequency is a good choice.
The bandwidth corresponds to how fast the loop response is, so higher bandwidth means the output voltage can recover much more quickly during load transient.
Here is a design tool/checklist to help…

Using the calculator, I have entered the value of capacitors in my feedback network taken from the Webench report (both attached)

Hi Lalit
The resistor divider looks ok. Keep the C3295 330pF as a placeholder but do not populate the capacitor.
To review the overall schematic, I have attached a calculator/checklist to help with this.

Hi Britton,
I have updated and filled in the required information based on the current schematic and design parameters.
You may now proceed with the verification and review. Please let me know if any clarification or additional details are required…
