please help me.....my shunt regulator in DER298(attached herein) is not working. The current output is much larger at 220Vac......I should have the same current output at universal input.
I made the same circuit as the DER298 suggested.

please see the attachment. The attached files are from DER298 from design samples of LNK419
Are you trying to duplicate DER298 ?
Do you need DER298 gerber file?
Yes, I am trying to duplicate it then after I got everything right,then I might increase it to 23W. I already made the pcb board.
If you have a gerfile for troubleshooting better to send it.
The gerber file is available in the

RD298 folder.
Please attach your schematic and inductor design.
Also what is your output voltage?
