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,
·
P ( max ) = V IN ( max ) × I LIM ( max )
= 5.5 × 1.5 = 8.25W
(5)
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 IN , V OUT and GND will help
minimize parasitic electrical effects along with minimizing the
case to ambient thermal impedance.
