Functional Settings
1. Soft Start
CE and soft start (SS) functions are commonly assigned to the CE/SS pin. The soft start function is effective until the voltage at the CE pin
reaches approximately 1.55 V rising from 0 V. Soft start time is approximated by the equation below according to values of Vcont, Rss, and
Css.
T = -Css

ln((Vcont - 1.55)/Vcont)

ln ((5 - 1.55)/5) = 17.44 ms.
Set the soft start time to a value sufficiently longer than the period of a clock pulse.
