Hi Alice,
With lower Vin such as 5V, the power loss is expected to be slightly higher if all other conditions kept same. The max load current possibly will be limited by the thermal design comparing to Vin=12V.
What will be the Vout, switching frequency, and output inductance you plan to use?

Hi Qingquan,
Hi Alice,
Thank you for the update.
Based on my understanding, you should be able to get 30A continuous current with proper PCB layout and thermal design.
However, the switching frequency upper range is too high, we recommend max frequency to be 1.25MHz.

Hi Qingquan,
If we set the switching frequency to be 1.2MHz, do you think we can get at least 30A continuous current?
Just wanted to be sure if I need a boost converter in my design. Or if there is another similar part available I can use?
Hi Alice,
With high switching frequency, high switching loss is expected, so I would expect higher power loss and you may need to be even more cautious about the thermal design.
Any specific reason you need so high switching frequency?
Anyway, if the thermal had been properly taken care of, 30A continuous current is still possible.
If you prefer to have higher design margin, I would suggest CSD95495 with higher current rating and in same package. So you can try with CSD95496 first and still can swap to CSD95495 later with no other BOM change required.
Best,
Qingquan
