of the board during short-circuit operation. Thanks to the narrow operating time with respect
to the off-time, the average output current as well as the average primary current are limited.
This will avoid converter overheating and consequent failures. Removing the short allows
the board to resume normal operation.

the LLC stage. The open loop operation provides an increase also of the auxiliary voltage
that will trigger the L6599AT pin #9 (DIS) protection pin via the Zener diode D17. As
a consequence, the L6599AT will shut down, stopping the operation. The L6599AT will
activate also the PFC_STOP pin (#9) that will stop the PFC too, thus both controllers will no
longer be powered by V
a new startup cycle will take place. This sequence continues until the open loop is removed.

reaches the enable level set via the L6599AT LINE pin, even the LLC stage starts switching
