FPF2123-FPF2125 Rev. C
F
This is more power than the package can dissipate, but the
thermal shutdown of the part will activate to protect the part
from damage due to excessive heating. When using the
FPF2124, attention must be given to the manual resetting of the
part. Continuously resetting the part when a short on the output
is present will cause the temperature of the part to increase.
The junction temperature will only be able to increase to the
thermal shutdown threshold. Once this temperature has been
reached, toggling ON will not turn-on the switch until the
junction temperature drops. For the FPF2125, a short on the
output will cause the part to operate in a constant current state
dissipating a worst case power of,

=
This large amount of power will activate the thermal shutdown
and the part will cycle in and out of thermal shutdown so long as
the ON pin is active and the short is present.
Board Layout
For best performance, all traces should be as short as possible.
To be most effective, the input and output capacitors should be
placed close to the device to minimize the effects that parasitic
trace inductances may have on normal and short-circuit
operation. Using wide traces for V

and GND will help
minimize parasitic electrical effects along with minimizing the
case to ambient thermal impedance.
