Hi
Here are my comments:
1. Yes, the voltage of the BOOT cap should be higher than 2.1V (typ). BOOT is used to supply for the driver of the highside MOS. if the voltage of the boot cap is less than the threshold voltage of the highside MOS, the MOS…
Hello,
Thank you for sharing this information and your schematic.
I reviewed the schematic and please see my feedback below. Based on my review, I believe that a potential problem is that the design is unstable. Based on my calculations, I think the…
Hi Nicky,
What I mean is the bandwidth of the signal for this measurement? You can limit the bandwidth of a trace which would could hide potential noise.
Second, I looked at the compensation calculator, and please see my recommendations below:
Rcomp…
I have find the calculation excel sheet for TPS54560 inverting buck design on its website. Now I have calculated all the values for inverting design and will try on circuit asap. I hope it will work for 3 Amps.
By the way I would like to ask another…
0647.AM571X_REV1_1A.pdf Hi, Shiou Mei,
Thanks for quick response.
The target board is not working yet. Below are the answers to the questions.
. Is this an existing working platform you re-designed the PCB for?
No, this is the first prototype…
