Functional Description
Version 1.3
12
15 Sep 2004
Once the malfunction condition is removed, this block
will then turn back on. The recovery from Auto Restart
Mode does not require disconnecting the SMPS from
the AC line
When Active Burst Mode is entered, the internal Bias is
switched off in order to reduce the current consumption
to below 1.05mA while keeping the Voltage Reference
active as this is necessary in this mode.

Startup Phase
Figure 7
Soft Start
At the beginning of the Startup Phase, the IC provides
a Soft Start duration whereby it controls the maximum
primary current by means of a duty cycle limitation. A
signal V
which is generated by the external
capacitor C
Softs
in combination with the internal pull up
resistor R
, determines the duty cycle until V
SoftS
exceeds 4V.
When the Soft Start begins, C
is immediately
charged up to approx. 1V by T2. Therefore the Soft
Start Phase takes place between 1V and 4V. Above
V
SoftsS
= 4V there is no longer duty cycle limitation
DC
which is controlled by comparator C7 since
comparator C2 blocks the gate G7 (see Figure 6). This
maximum charge current in the very first stage when
V
SoftS
is below 1V, is limited to 1.32mA.
Figure 8
Startup Phase
By means of this extra charge stage, there is no delay
in the beginning of the Startup Phase when there is still
no switching. Furthermore Soft Start is finished at 4V to
have faster the maximum power capability. The duty
cycles DC
and DC
are depending on the mains and
the primary inductance of the transformer. The
limitation of the primary current by DC
is related to
V
= 4V. But DC
is related to a maximum primary
current which is limited by the internal Current Limiting
with CS = 1V. Therefore the maximum Startup Phase
is divided into a Soft Start Phase until t1 and a phase
from t1 until t2 where maximum power is provided if
demanded by the FB signal.
