This is an output voltage status signal that is open col-
lector and is pulled low when the output voltage falls below
Overvoltage can be sensed by either connecting FB1s
and FB2s to their corresponding outputs through sepa-
rate output voltage divider resistor networks, or they
The iP1201PbF provides thermal shutdown. The thresh-

performed by recycling the ENABLE pin.

outputs. The PGOOD pin can be left floating if not used.

exceeded, thermal shutdown turns the outputs off. Ther-
mal shutdown is not latched and automatic restart is ini-
tiated when the sensed temperature drops to the normal
range.
