TPS54160: Can we use TPS54160 as a negative output buck

Part Number: TPS54160

Hi team,

My customer wants to convert 24V input to -20V/1W output. I found TPS54160 might be a good choice. We just need to connect negative output to its GND pin and connect positive output to the reference GND. And TPS54160's Vinmax>24V+20V.

But I just want to double check with you if TPS54160 is proper here. Is there any other restriction inside TPS54160 to stop it working as a negative BUCK? If it is not proper, do you have any other recommendation? Thanks.

Best regards,

Wayne
