POWER FACTOR CORRECTION
3. In normal operation, when the power supply is un−plugged, the bulk voltage goes down. At a first crossed level, the PG pin opens. Later,

when the bulk crosses a second level, the LLC turns off. There is no timing link between these events, except the bulk capacitor discharge
slope. However, if for an unknown reason the PFC is disabled (fault, short−circuit), the PG pin immediately opens and if sufficient voltage
is still present on the bulk (e.g. in high line condition), the LLC will be disabled after a typical time of 5 ms.
