I'm very new to the world of electrical design. I'm trying to create a SMPS circuit on eagle and am struggling to find the right transformer. I'm currently following this circuit (page 7): https://www.power.com/sites/default/files/PDFFiles/rdr158.pdf
I'm having trouble finding a transformer like this. The one listed in parts is the have bias windings on opposite side (might be a stupid question). Does this not matter as they are used for control? Also is there anything I should watch out for in terms of the specific capacitors, diodes, and resistors I pick. Any help would be greatly appreciated!
