NCP1392B, NCP1392D
The dimming feature can be easily aid to the ballast
application by adding two bipolar transistors (Figure 14).
Transistor Q2 pullup BO input when dimming signal is high.
V bulk
In the same time the Q1 discharges soft start capacitor via
diode D1. Ballast application is enabled (including
soft ? start phase) when dimming signal becomes low again.
