10.3 Startup behavior
During power up when the V
OUT
is less than 96% of the rated level, internal voltage loop output increases
from initial voltage under the soft-start control. This results in a controlled linear increase of the input current
from 0A thus reducing the current stress in the power components as can be seen on the yellow wave shape
in Figure 14.
