Part Number: TPS546C20A Other Parts Discussed in Thread: TPS546C23 , I am facing two issues with TPS546C20A on a single phase design.
Input: 12V
Output: 0.845V 30A
Issue 1: On the measured loop gain, at the low frequency region (1kHz to 4kHz, see Case…
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 the…
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.…
Other Parts Discussed in Thread: TPS40021 When I want to change the input capacitance it opens a new window with Bad url request - How can I fix this? I don't want to start new design.

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 verify…
Hello Anthony,
Please provide the updated TPS40KType spreadsheet that you used prior to making the last recommendations for the compensation network values.
Please see attached.
