For example:
To minimize power loss on this resistor, choose a high-
er value for R1 than the one calculated above (if a
longer startup time can be tolerated).
The above startup method applies to a circuit similar to
the one shown in
Figure
1. In this circuit, the tertiary
winding has the same phase as the secondary wind-
ings. Thus, the voltage on the tertiary winding at any
given time is proportional to the output voltage. The
minimum discharge time of C1 from 22V to 10V must
be greater than the soft-start time (t
SS
).
