3.9 Soft start capacitor
Considering the soft start equations:
C
SS
= 150pF
The equations are valid without load. When an active load is present the equations result more complex; further
some active loads have unexpected effect, as higher current than the expected one during the soft start, can
change the start up time.
In this case the capacitor value can be selected on the application; anyway the Eq11 gives an idea about the
C
SS
value.
