5-3. Overvoltage 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 stopped. When the PFC output voltage returns to
within 5.5% of the prescribed voltage, operation of the OUT pin is resumed.
