Mode 2 – ON & OFF through STANDBY
This mode can be seen as a mixture of mode 0 and
1. Here the inserted stand by mode is actually
nearly the same as the ON state but with the output
forced to zero (compared to mode 0). An interlock
puts the power supply immediately in the FAULT
state.
In the stand by mode the output converter is
with
power but forced to zero output.

The STB transition is locally initiated by pressing
the reset button and thereafter at the same time the
