Hi folks, so I am making this smps based on SG3525 driving an IR2110 which then is driving two half bridge mosfets.
now i made the smps to have two separate units, one meant to drive each channel of an amplifier.
for the first smps unit i got an older 3c85 ferrite core which i wound as the circuit of the smps advised with 12 turns pirmary (even though the cirucit also showed to use an etd59 core) , now for the second I have at hand a misterious ferrite core that i once bought in a local radio shop it has the code on it which reads F1 67 and that's it , when i google that i get no results.
my question is can I just use it, maybe wound some few more turns on it just in case because i think it has a lower permeability than the higher end cores which cost more and so on.
also is it true that everything else being the same a core with a lower permeability would need more turns to have the same extent of magnetization of the core in each half cycle of AC passing through the windings?
P.S. just in case I will attach the schematic if that helps determining whether i can use this core or not.
