Soft stop time
Soft start is exercised with the EN pin set high. Current
control takes effect at startup, enabling a moderate
output voltage “ramping start.” Soft start timing and
incoming current are calculated with formulas (2) and (3)
below.
Soft stop is exercised with the EN pin set low. Current
control takes effect at startup, enabling a moderate
output voltage. Soft start timing and incoming current are
calculated with formulas (4) below.

When output voltage (Is-) falls to REF×0.7 or less, SCP
comparator inside IC is exercised.
If the status of High is continued 1ms or more
(programmed time inside IC), the IC goes OFF. It can be
restored either by reconnecting the EN pin or disabling
UVLO.
