Current Limiting is now possible in a very accurate way.
E.g. I
= 0.5A with R
= 2. Without Propagation
Delay Compensation the current sense threshold is set
to a static voltage level V
=1V. A current ramp of
dI/dt = 0.4A/μs, that means dV
/dt = 0.8V/μs, and a
propagation delay time of i.e. t
=180ns
leads then to an I
overshoot of 12%. By means of
propagation delay compensation the overshoot is only
about 2% (see Figure 14).
Figure 15
Overcurrent Shutdown
The Propagation Delay Compensation is realized by
means of a dynamic threshold voltage V
(see Figure
15). In case of a steeper slope the switch off of the
driver is earlier to compensate the delay.

Control Unit
The Control Unit contains the functions for Active Burst
Mode and Auto Restart Mode. The Active Burst Mode
and the Auto Restart Mode are combined with an
Adjustable Blanking Window which is depending on the
external Soft Start capacitor. By means of this
Adjustable Blanking Window, the IC avoids entering
into these two modes accidentally. Furthermore it also
provides a certain time whereby the overload detection
is delayed. This delay is useful for applications which
normally works with a low current and occasionally
require a short duration of high current.

is clamped at 4.4V by the closed switch S1 after
the SMPS is settled. If overload occurs V
is
exceeding 4.8V. Auto Restart Mode can’t be entered as
the gate G5 is still blocked by the comparator C3. But
after V
FB
has exceeded 4.8V the switch S1 is opened
