Figure 51. At power on, output A is first activated and the frequency slowly
decreases via the softstart capacitor.
Figure 51 depicts an autorecovery 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 VCC
(min)
comparator stops the output pulses whenever it is activated,
that is to say, when V
CC
falls below 10.3 V typical. At this
time, the V
CC
pin still receives its bias current from the
startup resistor and heads toward VCC
ON
via the Vcc
capacitor. When the voltage reaches VCC
ON
, a standard
sequence takes place, involving a softstart. Figure 52
portrays this behavior.
