RE: Transformer for TNY279P flyback converter
Hello there,
We are in the process of designing an AC-DC converter with the requirement of converting 214 DC from a Bridge rectifier to 5V DC at a power rating of 15W. After thorough evaluation, we have determined that the TNY279P flyback controller is the most suitable for our needs.
In this we are new to flyback transformer design so could you please provide the exact flyback transformer part number and specifications ? This information will enable us to commence our design immediately. If the part number is not available, kindly provide the precise transformer design details so that we can forward the specifications to Würth Electronics and request them to manufacture the transformer for us.
We would appreciate receiving the requested inputs at your earliest convenience.
Annual Production: 100,000 units
Thanks,
Sakthivel

Hello Sakthivel,
Good afternoon and thank you for choosing Power Integrations devices.
Kindly refer to the attached file for a 15 W flyback design using TNY279P. You can find the specific transformer design on page 7 and 8. Let me know if you need anything else or if you have any questions and clarifications regarding the attached file.
Thank you and have a great day ahead.
Regards,
