I have to supply my power analyser design. I need one output for main parts (analog, logic, LCD, etc.) and one for isolated RS485 interface.
I was looking at some similar reference designs and i create simple solution using TNY267 and HAHN V50116 transformer.
Can someone with more experience (this is my first SMPS design) just take a look at my design and comment it?
My idea is to use 12V output with some LDO's to provide 5V and 3V3 to main parts and second 5V output just as it is to supply isolated side of RS485 transceiver.
