... IC is still kept in the off-condition. In this case the voltage at pin 8 is between the thresholds of comparators K2 and K3. During the bright phase the voltage at pin 8 is above the K2 threshold, during the dark phase it is below the K3 threshold. For proper start conditions a minimum lamp wattage required. 4726C–AUTO–02/10 U6043B 5 ...
