TPSM846C23: Power module suggestion

Tool/software:

Hi,

I need a power module with below specifications 

1. Input voltage-5V

    Output voltage-0.68V

    Output Current-61.58A

With PMBUS feature and remote sensing 

  so I need a power module with current rating nearly twice the output current

Or suggest stacked power modules for the above specification 

2. Input Voltage-5V

    Output Voltage- 0.75V

     Output Current - 40A

   With PMBUS feature and remote sensing

   I need a power module of nearly 60A to 80A or stacked power module.

Thanks
