TOP265 doesn't move by the design value with PI Expert.

Posted by: kawakami on

IC doesn't move by the design value with PI Expert.
Use IC is TOP265KG.
At line voltage AC80V, please undertake in the design maximum.
When I turn on, output doesn't establish it.
Please fall to 0V without a feedback circuit's moving.
The control voltage is the situation that 4.38V is being repeated from 5.75V.

The outside designated by PI Expert  CONTROL  The capacity of the pin condenser.
When O is increased, I tend to improve.
What kind of thing is considered by a factor?
Outside  CONTROL  But the capacity of the pin condenser is increased.
Is there a way to improve?

Dear kawakami,

 

We are having some difficulty understanding your exact question.  Please feel free to clarify perhaps by simplifying the question and making it very specific.  Thank you.
