Hello Ancy
Unfortunately, it is not possible to replace TPS40005 with TPS40057 without a redesign.
If any chance to redesign, please consider; LM5145 75V Synchronous Buck Controller With Wide Input Voltage and Duty Cycle Ranges https://www.ti.com…
Hi Uchikoshi,
LM5146 is the same family as LM5145.
You can use LM5146 EVM as well.
https://www.ti.com/tool/LM5146-Q1-EVM12V
However for 24V to 12V/2A you can use a converter or module for easier design.
Hope this helps,

Hi Gabriel,
Please attach that quickstart you took the bode plot from?
Note Phase margin should be larger than 45 degrees, and 58 degrees (on that plot) is OK.
The capacitor ESR will help with stability and phase margin, however output voltage ripple…
