Part Number: TPS54KB20 Tool/software: EVEN THOUGH R limit resistor value select to 4K32 for 25A current limit , 3.3V output voltage is collapsing when output current exceeds 7A . all value selection is made based on application reference circuit published…
Hi Hideki-san,
My first suggestion is that the part may be latching off due to UVP during startup. Could you increase the soft start time and see if that resolves the issue?
My second thought is related to VCC. Please check to ensure that VCC remains…
Part Number: TPS54KB20 Hi Team,
Do you have detailed description and block diagram of KB20 DS 6.3.7? What is the difference between D-CAP4 and other D-cap versions? Thanks!

Part Number: TPS54KB20 Hello TI team, I am looking for pspice model to simulate TPS54kb20, I did a research in TI website but nothing was found. Can you please send the the Pspice model. Thank you.
Part Number: TPS54KB20 Hi expert,
Customer is requesting TPS54KB20 CAD file in .dxl(unit:mm). We download from product folder but it turns out nothing.
Could you please help clarify what might goes wrong?
Thanks,

Part Number: TPS54KB20 Hi,
I am confused by the descriptions below when viewing the datasheet. Does it mean that output voltage will always have a drop when it is high prebiased?
I do not think it is a good behavior as the leakage from one rail to other…
Hi Sharat,
Are you referring to using the TPS54KC23 in an inverting buck-boost topology, as described in this application note? https://www.ti.com/lit/ds/symlink/tps54kb20.pdf
If that's the case, the setup effectively involves converting 17V to 5V with…

we are planning to use similar part for TPS82085SILT with input voltage of 12V to 2.2V output, can…
Hi Yishan,
We don't have P2P part with TPS54821. But similar part with different package: TPS56C215, TPS53353, TPS54KB20 and TPS548B28.
Hope this helps,
Thanks,
Nancy
