The overvoltage detection is provided by Comparator
C1 only in the first time during the Auto Restart Mode
till the Soft-Start voltage exceeds the threshold of the
Comparator C2 at 4.0V and the voltage at pin FB is
above 4.8V. When VCC exceeds 16.5V during the
overvoltage detection phase C1 can set the Error-Latch
and the Burst Phase during Auto Restart Mode is
finished earlier. In that case T

prevented from overvoltage detection due to varying of
VCC concerning the regulation of the converter output.
When the voltage V
detection by C1 is deactivated.
3.8.3
Thermal Shut Down is latched by the Error-Latch when
junction temperature T
exceeding an internal threshold of 140°C. In that case
the IC switches in Auto Restart Mode.
