... MOSFET and diode. To protect against this, FL7930 internally checks if the input AC voltage exists. If input © 2011 Fairchild Semiconductor Corporation FL7930 • Rev. 1.0.0 does not exist, soft-start is reset and waits until AC input is live again. Soft-start manages the turn-on time for smooth operation when it detects AC input is applied, which applies less voltage and current stress on startup ...
