For a 5V input and 1V output, the maximum possible
power dissipation per switch is:
P = 0.5 x (1.5A) x (5V - 1V) = 3W
Since the package power dissipation is limited to
1952mW, the MAX1558/MAX1558H die temperature
exceeds the thermal-shutdown threshold and the
switch turns off. After the die temperature cools by
10
°C, the switch turns on again. If the fault-overload
condition continues, the switch cycles on and off with a
duty cycle and period that is a function of the ambient
temperature and PC board layout.
A short across the output for more than 20ms places
the part in autoreset mode. With VIN_ = 5V and an
autoreset test current of 30mA, the power dissipation
for a short-circuited output is given by:
P = (30mA) x 5V = 0.15W
