I am currently following the TOPSwitch264 reference design DER-237.

The reference design has a detailed description for the winding of a custom transformer on an RM6 core.

Do you know of any standard Transformer available (from any manufacturer) which can be purchased directly from them, that would meet the transformer requirements for the DER-237 design? This would mean that I would not need to use a custom wound transformer which is preferable for this particular application.

Thanks,
Calum
