Thanks for Posting your question into forum and we appreciate your time and Patience.
We did Calculated your total power which is coming around 5 W , Input power at 85 Vin is 14W, Efficiency is too Low.
Please make sure your transformer is designed as Per Out PIXL's Spreadsheet according to your specifications. Please Run your transformer design using our spreadsheet and make sure it's matching your inductance. We recommed to use the transformer as per the spreadsheet.
