Output Over Voltage Protection
The output over-voltage protection consists of an output Zener diode that monito
rs the voltage on the output
terminals. If the voltage on the output terminals exceeds the over-
voltage protection threshold, then the Zener diode
clamps the output voltage.
Short Circuit Protection
Continuous, hiccup and auto-recovery mode.
During a short circuit condition the converter will
shut down. The average current during this condition will be very
low.
Thermal Consideration
Theconverter operates in a varietyof thermal environments. However, sufficient cooling should be provided tohelp
ensure reliable operation of the unit. Heat is removed by conduction,convection, and radiation to the surrounding
environment. Proper cooling can be verifiedbymeasuring the point as thefigure below. The temperature at this
location should not exceed 100°C.Whenoperating,adequate cooling must be provided to maintain the test point
temperature at or below 100°C.Although the maximum point temperature ofthe converter is 100°C, limiting this
temperature to a lower value will yield higher reliability.
