Where is the Forum "Search" Feature?
Hello,
Sorry ...new to the PI forums, but to avoid re-posting an already-answered question, where can I find the forum search function?
I looked around but seem to be missing this.

Hi -
I have your IC in about a 30 watt supply putting out 5 & 20Vdc.
There is a stability problem when adding the overvoltage zener, otherwise it acts fine.
I am including a bit map schematic and layout to help your diagnosis.
You may contact me at tom.dawson@siliconengines.net or by phone at 224-795-5372. Please email me if you can because I am harder to reach by phone. Are there problems with C22, C23, C20 being ceramic, or is there any problem with the layout? this is a 2 layer pcb.
Thanks,
Tom Dawson

Thanks for Posting your question, Could you please explain at what load you are seeing stability problem. Do you have output voltage oscillations, I really like to understand at what line and load condition your seeing output stability? Please explain us clearly.

Good question! Site search results include relevant forum posts, so just use that.
