The IC provides several protection features which are
separated into two categories. Some enter Latched Off
Mode, the others enter Auto Restart Mode. The
Latched Off Mode can only be reset if VCC is falling
below 6V. Both modes prevent the SMPS from
destructive states. The following table shows the
relationship between possible system failures and the
chosen protection modes.

The VCC voltage is observed by comparator C1 if 21V
is exceeded. The output of C1 is combined with the
output of C4 which observes FB signal if 4.8V is
