L6563S enhanced transition mode PFC controller (2)

In essence, the circuit person adds the offset of the connection time of the power switch. The voltage of the line voltage is over zero. When the transient line voltage increases, the offset decreases, so when the line voltage moves to the top of the sine curve, it can be ignored. In addition, the offset is the voltage modulation on the VFF pin (see the ""voltage feed"" section), so that t...
