As far as I understand the flyback topology, it can be used in both buck and boost converters.

What I am not sure about is: Does it also work for the case where buck-boost is needed, i.e. Vin,min <= Vout <= Vin,max\$V_{\text{in,min}} \leq V_{\text{out}} \leq V_{\text{in,max}}\$?

I think it should, but googling the topic immediately leads to the SEPIC converter. Also, I know that isolated SEPIC is possible, but I rarely see design examples.

Could you give me some idea on what topology to use for the specific case of:

9 < vin < 24 V\$9 < v_{\text{in}} < 24 \text{V}\$ for vout = 12 V\$v_{\text{out}} = 12 \text{V}\$ at 1 A, galvanically isolated

Now I know this question i a very basic one, but I think it is specific enough to be legitimate here..
