Ah, okay.

Das mit dem Übersetzungsverhältnis macht man primär um den Schalter zu schützen?

Weil wegen:

Zitat:Actually this is the big advantage of a flyback converter over a boost converter. In a boost converter the switch (MOSFET) has to carry a large current during the on phase and a high voltage during the off phase. In the flyback converter the voltage during the off phase is transformed down to a value determined by the ratio in turns. This means that a MOSFET with a much lower Ron can be used (see section on the boostconverter).

Gerade mal die Last ein wenig variiert, schwankt doch schon ganz schön am Ausgang. (10mA -> 30mA)

Ich frage mich immernoch wie Linear das macht:

Anbei der aktuelle Stand.
