MPQ2908A Max. load current

Hi all.

What is the maximum Iout current supported by the MPQ2908A IC?
I need to confirm whether I only need to consider the load (current) applied to the external MOSFET when applying it to an actual design, or whether I should also consider the load applied to the IC itself.

Intended load: 48Vin, Vout 12V @ 20A = 240Watt

The application note states that load sharing was used. Is it absolutely necessary to use the same configuration?

Thank you.
