iP1202PbF
Refer to iP1202PbF Design Procedure section on
how to set the OVP Trip threshold.
PGOOD
This is an output voltage status signal that is open
collector and is pulled low when the output voltage
falls below 85% of the output voltage. High state in-
dicates that outputs are in regulation. There is only
one PGOOD for both outputs. The PGOOD pin can
be left floating if not used.
Thermal Shutdown
The iP1202PbF provides thermal shutdown. The
threshold typically is set to 140°C. When the trip
threshold is exceeded, thermal shutdown turns the
outputs off. Thermal shutdown is not latched and au-
tomatic restart is initiated when the sensed tempera-
ture drops to the normal range.
