LTM8064 and other uModules at LTpice

I tried simulating LTM8064 and LTM8073 at LTspice(in the company default test fixture), but the Input current had high and unacceptable ripples(6-8A).

Does anyone else had the same phenomena? Also the RMS current was very high..

I tried to add input capacitance but it didn't help.

Thanks,
