Figure 13.
The figure above shows a typical VCC arrangement to satisfy
timing requirements.
Transistor QA is enabled during remote on condition. Capacitor
C2 will charge through D1 while C1 is charged through R1.
SENZero will turn on ahead of PFC IC. Diode D2 makes C2
voltage tracks C1 voltage. Capacitor C2 can be increased to
ensure that during turn-off, PFC turns-off first before SENZero.
Capacitors C1 and C2 can be 100 nF standard decoupling
capacitors. However, C1 needs to be ≥C2.
