Application information
consumption and drops more until the Vccrestart threshold is tripped. Now, the high voltage
start-up generator restarts and when the Vcc crosses again its turn on threshold the IC
starts switching. In this manner the power is transferred from mains to PFC output only
during a short time for each Trep cycle.
