LTM8057 GND Connection

Hello,

Does anyone know how the LTM8057 will behave/perform if the output GND gets tied back to the input reference GND? We have been using the device to generate an isolated 5V digital supply and isolating all our digital signals with ADUM141 ICs. Our potential customer's system does not use isolation between system ground and digital ground and therefore will basically tie our references together when the systems are connected.

Any ideas on what issues this may cause for the LTM8057 if any. I have a separate post asking about the ADUM141 but feel free to share your knowledge on that as well.

Thanks,
