Part Number: TPS92692
Input voltage range is 9V~36V, normally working at 12V or 24V.
Output is 19.5V/1A.
Please help to confirm schematic and component parameters.
Is it necessary to modify?
From my initial review, R8 should be 0 Ohm to begin with and raising it in EMI testing if needed. R8 gate resistance of 100 Ohm is also quite high.
You also do not need R4 or VR1 since this is taken care of the the PDRV of the TSPS92692 already. With DIM/PWM input is being pulled high you will not need to have R13 unless you are PWM'ing.
4.7nF (C24) seems to be high for a snubber and I would recommend using 470pF to begin with.
What is the part number for L3 or saturation current of L3?
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Tuan Tran74:
Below is the L3 currently selected.
I choose the 47uH to test first. If the temperature is too high, I will choose 33uH.
BTW, C9 and C12 is use MLCC instead of electrolytic capacitors. Is that ok?
