Hi Sir !, I need to design a circuit with the parameters as above. After learning the datasheet, I decided choose TOP227. But now I known that PI Expert has stopped support with TOPSWITCH II-family therefore I can't simulate my circuit with TOP227. So I would like to get your advice on this issue. Thank you so much!

Dear Thanh20153404,

Thank you for using Power Integrations.
The TOPSwitch you want to use is no longer recommended for new designs.
We have TOP JX and HX that are now available.
Please make use of them.
