ADuM3070 datasheet contains following efficiency graph:

I plan to use 5V input voltage and 3.7V output voltage with 5mA maximum (1.5mA typical) load current. I would like to create effective isolated power supply for light loads (1-5 mA). Could you please recommend me right transformer or isolated solution for achieving maximum efficiency at small loads (3.7 V, 1-5 mA)?
