LIGHT LOAD OPERATION
At light load conditions, the device skips switching cycles in order to keep the output voltage regulated as well as to increase
the efficiency under this condition.
SOFT-START
In order to prevent the output voltage from overshooting during start-up, a soft-start is implemented. The soft-start is internally
set and lasts around 1.3ms for both the 173010342 and 173010542. The figure below shows a start-up example, in this case
with 173010342.
