IMX7/IMS7 DC-DC Series Data Sheet
7-Watt DC-DC Converters
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.
In order to protect the converters, transient suppressors are
fitted to the input; see table below:

1 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.
2 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.
To achieve IEC/EN 61000-4-5, level 2 compliance, an
additional inductor and capacitor should be provided externally
as shown in the figure below. The components should have
similar characteristics as listed in table 4.
Input Fuse and Reverse Polarity Protection
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:
– 20IMX7 and 24IMS7 a fast 2 A (F2A) fuse
– 40IMX7 and 48IMS7 a fast 1 A (F1A) fuse
– 70IMX7 a fast 0.63 A (F.63A) fuse
– 110IMX7 a fast 0.63 A (F.63A) fuse.
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.

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.
