I use EVAL-ADP1048 that have the input voltage accuracy issue.
The ADP1048 set VIN On = 85V rms and VIN Off = 80V rms that have 3%~5% error.
Please see the attachment that VIN On = 85V rms and VIN Off = 73V rms actually.
And i input voltage 80V rms that VAC_OK light turn-off but the output will keep work.
While i input voltage 73V rms that VAC_OK light turn-off and output off.
Could you tell me that was correct? Or ADP1048 have input voltage 3%~5% error?
