L6699D No load condition

Hi All,

I have a 500W PS build around the L6699D and everything is working good.

Now I found 1 little thing:

If I run the unit in No Load the output is 24Vdc if I take the input voltage (AC) away the output drops a little.

Now if I switch the unit back on the output voltage flies up and clamps to the OVP (30Vdc) and it is unable to regulate the voltage down despite that the signals are there.

Now my question is, is this someting I can control or is this a problem in the L6699D?

Hope someone can help me.

Thanks,

Patrick
