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,

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: TPS40304 , TPS40305 , TPS40303 Customer reports that FSS will not always be enabled at startup using the recommended 267kOhm resistor. Is this indicative of hidden features?
In addition to the above observation, the customer…
Other Parts Discussed in Thread: TPS40195 , TPS40303 , TPS40101 , REF3025 I have designed the TPS40195 for 1V/10A. The MOSFET I use has an R DSON(min) =5mOhm and R DSON(max) =7mOhm. If I design my I SCP(min) to 12A, I get a I SCP(max) of 37A acc. to the equations…
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…
