Output Over Voltage Protection
The output over-voltage protection consists of a Zener diode that monitors the voltage on the output terminals. I
f
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, the converter shut s down.Theaverage current during this condition will be very low .
Thermal Consideration
Thepower module operates in a variety of thermal environments. However, sufficient cooling should be provided
to help ensure reliable operation of the unit. Heat is removed byconduction, convection, and radiation to the
surrounding environment. Proper cooling can be verified by measuring the point as shown in the figure below.The
temperature at this location shouldnot exceed 100°C.When operating,adequate cooling must be provided to
maintain the test point temperature ator below 100°C.Althoughthe maximum point temperature ofthe power
modules is 100°C, limiting this temperature to a lower value will yieldhigher reliability.
