... HA16174P/FP 4-2. Operation on a Momentary Outage (PFC operation hold on momentary outage: PFC hold function) (1) When the Momentary Outage is Short During a momentary outage, the voltage on the PFC-ON pin is discharged. When it reaches 1.6 V, charging of the capacitor on the DELAY pin starts. The voltage on the PFC-ON pin continues to fall and, when it reaches 1.4 V, source current begins to flow through the pin ...

... HA16174P/FP 5-3. Over Voltage Operation When the PFC output voltage is larger than 7.5% of the prescribed voltage due to an abnormality in the system or a sudden change of AC voltage or load, operation of the OUT pin is terminated. When the PFC output voltage returns to within 5.5% of the prescribed voltage, operation of the OUT pin is restarted. If the PFC output voltage rises to 20% above the prescribed voltage, the condition is considered definitely abnormal, and output of the PG signal is also stopped ...
