Hi Sirs,
Please tell me if you ever used myrra transformers in a TOPswitch flyback design.
I'm trying to do a 70 W power supply with TOP246 and 74050 transformer. Unfortunatelly the transformer has a different pinout from all I've seen in the documents,and it seems difficult to me to follow the rules of the PCB:short traces,minimum loops,etc.If you have a PCB layout for this circuit please help me.
Regards,Alex

I have no experience with Myrra but transformer sheet does include TOPSwitch as a possible device so seesm like it might work. As far as layout and whether tranformer meets our guidelines please read through TOP-GX App note available on this PI website. Also download PI EXpert transfomer design and device selection tool and compare transformer design to the one provided by Myrra.
