| Design ideas for a low-count part, low power isolated DC-DC power supply? |

I used these in the past: http://www.ti.com/isolation/transformer-driver/products.html With those transformers: https://katalog.we-online.de/en/icref/SN6501-Rev-G_Push-Pull_4?sid=3832d0653a |

Thanks for bringing the Royer converter. Indeed, it cannot be any simpler, component wise, than this converter. Although a caveat, if I recall correctly, is that the transformer core should employ a “square loop” material for optimal efficiency. But for the low power level involved, perhaps any power ferrite may be sufficient. |

You might consider a resonant royer... think royer but with the primary shunted with a capacitor. |
| Wolfgang:
Hi, a square hysteresis loop material is no requirement. A normal transformer is absolutely sufficient at small power levels. I used old ISDN transformers for my low-noise converters and some energy harversting experiments, also employing Royer converters: electronicprojectsforfun.wordpress.com/energy-harvesting/ |

Also, how many layers are you targeting? You might just stick the transformer inside the PCB... then the inductor is zero parts. Then you do resonant royer or forward or something. |
