Figure 42. SoftStart Behavior
Figure 43. A Typical Startup Sequence on an LLC
Converter
Please note that the softstart will be activated in the
following conditions:
A startup sequence
During autorecovery burst mode
A brownout recovery
A temperature shutdown recovery
The fast fault input undergoes a special treatment. Since
we want to implement skip cycle through the fast fault
input on the NCP1395A, we cannot activate the softstart
every time the feedback pin stops the operations in low
power mode. Therefore, when the fast fault pin is released,
no softstart occurs to offer the best skip cycle behavior.
However, it is very possible to combine skip cycle and true
fast fault input, e.g. via ORing diodes driving pin 13. In that
case, if a signal maintains the fast fault input high long
enough to bring the feedback level down (that is to say
below 0.6 V) since the output voltage starts to fall down,
then the softstart is activated after the release of the pin.
In the B version tailored to operate from an auxiliary
12 V power supply, the softstart is always activated upon
the fast fault input release, whatever the feedback
condition is.
