Soft--Start
The NCP101X features an internal 1.0 ms soft--start
activated during the power on sequence (PON). As soon as
V CC reaches VCC OFF , the peak current is gradually
increased from nearly zero up to the maximum internal
clamping level (e.g. 350 mA). This situation lasts 1.0 ms
and further to that time period, the peak current limit is
blocked to the maximum until the supply enters regulation.
The soft--start is also activated during the over current burst

(OCP) sequence. Every restart attempt is followed by a
soft--start activation. Generally speaking, the soft--start will
be activated when V CC ramps up either from zero (fresh
power--on sequence) or 4.7 V, the latch--off voltage
occurring during OCP. Figure 22 portrays the soft--start
behavior. The time scales are purposely shifted to offer a
better zoom portion.

Non--Latching Shutdown
In some cases, it might be desirable to shut off the part
temporarily and authorize its restart once the default has
disappeared. This option can easily be accomplished
through a single NPN bipolar transistor wired between FB
and ground. By pulling FB below the internal skip level
(Vskip), the output pulses are disabled. As soon as FB is
relaxed, the IC resumes its operation. Figure 23 depicts the
application example.
