LM5022: LM5022 PMP9446 Reference Design Question

Other Parts Discussed in Thread: PMP9446

Dear Team,

My customer is looking for Vin=12V and Vo=54V, Io=0.5A isolated circuit.

So I suggest PMP9446:

But the customer thinks the current transformer's cost is too high.

Can they get rid of this transformer and use a smaller resistor? ( Or you have another reference design)

I check this transformer's turn ratio is 100:1.

This transformer's only purpose is to reduce Rsense loss right?

If they want to remove this transformer, what is the resistor value they should use for Rsense?

BR
