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 iP1201 provides thermal shutdown. The threshold

FETs turn on, thus crowbaring the outputs. Reset is
performed by recycling the ENABLE pin.

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

ceeded, 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.
