Hibrid solution Isolated and no Isolated output
Hello,
I'm trying to design an power supply with one isolated output and 2 non isolated.
Using LNK6763V
Universal Input at 60Hz
Isolated output 5V 200mA;
Non-Isolated/Bias 15V/250mA - It Supply a MOSFET Driver used as phase cutting;
Non-Isolated 5V 100mA - Supply an auxilary circuito to indicate failure and status.
In attachament is my PIDesign, but I don't know how can I connect non-isolated referente to bias reference and generate a correct transformer manufacturer guide.
I appraciate for any consideration about my design.
Thanks
Leandro

I've uploaded a .pixls with 3 outputs + bias.
But I want a design with 1 isolated 5V/200mA output, and 2 non-isolated (bias 15/200mA + 5V/100mA).
I think these design is possible, but I do not known how design the transformer for that.
I appreciate your help.
Thanks

hi,
thank you for using PI-Forums,
can you check the attach file if its correct and can suit your needs.
-5v/200ma
-15v/200ma
-5v/100ma

Hello, nice!
Can I use the Bias reference (pin 4 of the transformer) as the reference for the non-isolated outputs (GND1)?
Thank you for help.

hi,
yes, you can connect (gnd1) to pin4 of the transformer (gnd of the primary side). the two outputs will become part of the primary side. provided that the user will never touch the 2 non-isolated output in your application.
thank you for using PI forums, I'm glad that I could help you.

Hi,
thank you for using the PI-forums.
i cant open/see the contents of the file you have attach (.uds file)
can you upload/share the file using the file extension (.pixls)?
thank you very much,
Regards,
Sigris
