I'm currently based in Singapore and would like to build this reference design to evaluate a 4-switch converter. I am unable to find a suitable part to replace the auxiliary flyback transformer employed in this design.
The description of this part in the BOM is:
540uH, 031-00019, XFMRS, Inc., Auxiliary Flyback Transformer, 540 uH, SMT SMD, 8-Leads, Body 400x300mil, Pitch 79mil
Could you ever so kindly recommend some alternative parts for me please?
