ADuM3470 Maximum Output Supply Current

James:

I think 165mA would be approximately the max output current to expect for 3.3V to 5V conversion.  I say approximately because if you use equation (1) on page 26 of datasheet you find that the turns ratio required would be greater than 2 (2.3), so the transformer needed for 3.3V to 5V would be the 1:3 turns ratio, part no JA4650-BL, but in this case using the circuit in figure 38.
