Figure 50. At power on, output A is first activated and the frequency slowly decreases via the soft--start capacitor
Figure 50 depicts an auto-- recovery situation, where the
timer has triggered the end of output pulses. In that case, the
V CC level was given by an auxiliary power supply, hence
its stability during the hiccup. A similar situation can arise
if the user selects a more traditional startup method, with
an auxiliary winding. In that case, the V CC(min) comparator
stops the output pulses whenever it is activated, that is to
V CC(on)
say, when V CC falls below 10 V typical. At this time, the
V CC pin still receives its bias current from the startup
resistor and heads toward V CC(on) via the V CC capacitor.
When the voltage reaches V CC(on) , a standard sequence
takes place, involving a soft-- start. Figure 51 portrays this
behavior.
