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

enter image description here

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!

The BOM and DIY design details are provided for you.

  • T1 Custom Transformer, EE16, 10pins;

  • \$\begingroup\$ Yea sorry I forgot to mention that but I was just curious to why the bias windings are in other side does this not matter as they are for control? Sorry if it's a stupid question \$\endgroup\$ – Abhishek Ravi Jun 4 '17 at 18:51
  • \$\begingroup\$ Secondary insulation is specified for 3kV, that's why layout order is as it is.. Primary windings are not... I would design it for 6kV if I lived anywhere with exposed power lines above ground to place of use, which might be 1 extra layer of tape if rated for 3kV between WD4 and WD5 \$\endgroup\$ – Tony Stewart Sunnyskyguy EE75 Jun 4 '17 at 18:54

Try Premier Magnetics: -

They do most of the link switch product range. See the link halfway down the page for the device you want to use.

Naive rather than stupid!

Also is there anything I should watch out for in terms of the specific capacitors, diodes, and resistors I pick

The circuit you linked has a very clear BoM so follow that and if something isn't clear get back and ask specifics. In other words look at the BoM: -
