IMX7, IMS7 Series Data Sheet  
7-Watt DC-DC Converters  
®
Note: Suppressor diode D is only necessary for 20IMX7 models.  
To withstand 150 V transients according to 19 Pfl 1, applicable for  
40 IMX7 models, the same external circuitry with similar  
components as for IEC/EN 61000-4-5, level 2 compliance can be  
used.  
Input Transient Voltage Protection  
In many applications transient voltages on the input of the  
converter may occur and are possibly caused by short circuits  
between Vi+ and Vi–, where the network inductance may  
cause high energy pulses.  
Input Fuse and Reverse Polarity Protection  
In order to protect the converters, transient suppressors are  
fitted to the input; see table below:  
The suppressor diode on the input also provides for reverse  
polarity protection by conducting current in the reverse  
direction, thus protecting the converter. An external fuse is  
required to limit this current. We recommend for:

Inrush Current  
The inrush current has been kept as low as possible by  
choosing a very small input capacitance. A series resistor  
may be inserted in the input line to limit this current further.

The built-in overvoltage trigger shuts down the converter at  
approx. 38 V protecting the input up to 50 V. For higher transient  
voltages an external suppressor or voltage limiting circuit as,  
e.g., for IEC/EN 61000-4-5, level 2 compliance should be  
provided.

If transients generating currents above the peak pulse current  
are possible, an external limiting network such as the circuit  
recommended for IEC/EN 61000-4-5, level 2 compliance, is  
necessary.
