TPS82130: Can this kind of Buck module be used to generate -2.5V/1A output by simply swapping VOUT and GND connection?

Hi team,

My customer needs to generate -2.5V/1A out from 5V system power. Considering limitation of PCB size, I want to propose them use our step down module, such as TPS82130. I am not very sure can this kind of module be used in this way? Say simply swapping its VOUT and GND connection (connect 'VOUT' of TPS82130 pin to system ground, and teat 'GND' pin as -2.5Vout). 

Thank you,

John
