... However, if the over voltage lasts so long that the output of E/A goes below 2.25V, then the protection is activated (static OVP) keeping the output stage and the external power switch turned off. The operation of the device is re-enabled as the E/A output goes back into its linear region. FM2827 Power Factor Correction Controller Ver 2.1 Specification ...
