IMX4 DC-DC Series Data Sheet  
4-Watt DC-DC Converters  
Thermal Considerations  
Output Overvoltage Protection  
If a converter, mounted on a PCB, is located in free, quasi-  
stationary air (convection cooling) at the indicated maximum  
The outputs of the IMX4 converters are protected against  
overvoltages by Zener diodes. In the event of an overvoltage  
on the output, the unit will shut-down and attempt to restart  
automatically. The main purpose of this feature is to protect  
against possible overvoltages which could occur due to a  
failure in the feedback control circuit. The units are not  
designed to withstand external overvoltages applied to the  
outputs.  
ambient temperature TA  
(see table: Temperature  
max  
specifications) and is operated at its nominal input voltage and  
output power, the case temperature TC measured at the:  
Measuring point of case temperature TC (see: Mechanical Data)  
will approach the indicated value TC max after the warm-up phase.  
However, the relationship between TA and TC depends heavily on  
the conditions of operation and integration into a system. The  
thermal conditions are influenced by input voltage, output  
current, airflow, temperature of surrounding components and  
surfaces and the properties of the printed circuit board. TA max is  
therefore only an indicative value and under practical operating  
conditions, the ambient temperature TA may be higher or lower  
than this value.  
Connection in Series  
The outputs of single or dual output units can be connected in  
series without any precautions, taking into consideration that  
the highest output voltage should remain below 60 V for SELV  
operation.  
Connection in Parallel  
Caution: The case temperature TC measured at the Measuring  
point of case temperature TC (see: Mechanical Data) may under  
no circumstances exceed the specified maximum value. The  
installer must ensure that under all operating conditions TC  
remains within the limits stated in the table: Temperature  
specifications.  
Several converters with equal output voltage can be  
connected in parallel and will share their output current quite  
equally. However, this may cause start-up problems at initial  
start-up, and is only recommended in applications where one  
converter is able to deliver the full load current, e.g, in true  
redundant systems.  
Short Circuit Behavior  
Typical Performance Curves  
The current limit characteristic shuts down the converter whenever  
a short circuit is applied to its output. It acts self-protecting and  
automatically recovers after removal of the overload condition.
