Hi Peter，

I designed a transformer to meet my needs through tools. I would like to ask you to help me check whether the parameters are reasonable.thank you.

Hello Tracy,

I believe these calculated component values are reasonable for your application.

I notice that the chosen value are a lot different from the calculated values.

For instance Lo is calculated as 446uH and you choose 200uH

Also the timing resistors are not close to the calculated values as are the UVLO,OVLO values.

I think you should consider changing your chosen component values and re run the calculator.

Regards

John
