Is it REFIN 1.8V nesessary to proper operation IR3555M with IRPS5401 in DCR sensing mode? (IOUT pin would be unused)

IR3555 datasheet is extremely short in compare with the IR3550 datasheet and does not allowed to draw conclusions by the functional block diagram.
Is it possible to obtain detailed IR3555 datasheet?

Thanks.

The completed datasheet can request through your local distributor with NDA. And the details are included.
