According to the schematic, you have teh PWRGD pulled up to Vout. So you will see Vout as teh PWRGD voltage when the output is within regulation.

Thank you for your replay, then why is written in the manual that PWRGD max value should be 6V. Just, i afraid of destroing the IC.

Yes the abs max for PWRGD is 6 V. You should not pull it up to a 10 V output. I have reqested that this be fixed in the SP software.

Yes, as John mentioned above abs max for PWRGD is 6V. The issue needs to be fixed in switcherPro. We will schedule it to be fixed in future version of the tool.
