I would like to use the LMG3410-HB-EVM with a +3.3Vdc supply.
In the reference design, the isolation transformers (T1 and T2) have a 1.3:1 turns ratio (P/N 760390014), such that with a +5Vdc supply the output voltage is ~14.8Vdc (including the diode drops). With a +3.3Vdc supply, the output voltage would be ~9.6Vdc, which is probably rather marginal.
If the transformers are swapped for units with a 1:1.1 turns ratio (P/N 760390012), then the output voltage would be ~13.9Vdc, which seems to be a better match. The new transformers have the same footprint as the reference design, but would need to be rotated 180deg with respect to the screen print in order to achieve the correct turns ratio.
Is this viable?

Greg
