Could you kindly help to check the Schematic?

Since when the input is 27V, and the board is under no load, then sometimes TPS54160 will be bad.

Hi Lian,

Could you clarify your definition of bad? Is it a higher output voltage ripple?
Also have you try entering your design specification in webench?

Thanks
