Is there a reference design for using the SN6505B to take 5V and turn it into 12V using a 5000Vrns transformer? Output Current from 12V will be 100mA but if the design supports more that would be ...

My question is if I use 12VDC in below circuit, and selected the transformer as WE 760390012 (1:1.1), but the related Vin of 760390012 is 5VDC, what's the problem of the transformer after that? And it ...
