... The turn-on and turn-off thresholds of the FSEZ1216B are fixed internally at 16V/5V. During startup, the hold- up capacitor must be charged to 16V through the startup resistor, so that the FSEZ1216B is enabled. The hold-up capacitor continues to supply V can be delivered from the auxiliary winding of the main transformer. V ...
