WebWurth Transformer 2024 - st.com WebMar 1, 2024 · For example, if the transformer is designed for 85..265 Vac (or 120..375 VDC) then this means that the output voltage will be 19 VDC and D will be nearly 0.5 at 120 VDC input in a proper designed flyback converter. Thus, if the input goes to 310 VDC (i.e. 220 Vac) then D decreases to 20%. Now let's think about this:
