SoftStart NCP1216A only
The NCP1216A features an internal 1.0 ms softstart
activated during the power on sequence (PON). As soon as
V
CC
reaches V
CCOFF
, the peak current is gradually
increased from nearly zero up to the maximum clamping
level (e.g. 1.0 V). This situation lasts during 1ms and further
to that time period, the peak current limit is blocked to
1.0 V until the supply enters regulation. The softstart is also
activated during the over current burst (OCP) sequence.
Every restart attempt is followed by a softstart activation.
Generally speaking, the softstart will be activated when
V
CC
ramps up either from zero (fresh poweron sequence)
or 5.6 V, the latchoff voltage occurring during OCP.
Figure 29 portrays the softstart behavior. The time scales
are purposely shifted to offer a better zoom portion.
