DC-DC Converters

IMX 7 Series

Input Transient Voltage Protection

In many applications transient voltages on the input of the

converter are always possible. These may be caused for ex-

ample by short circuits between Vi+ and Vi– where the net-

work inductance may cause high energy pulses.

To achieve IEC/EN 61000-4-5, level 2 compliance an addi-

tional inductor and capacitor should be provided externally

as shown in the figure below. The components should have

similar characteristics as listed in table: Components for

external circuitry to comply with IEC/EN 61000-4-5.

In order to protect the converters the IMX 7 types have a

built-in transient protection as per table below:

Please note: The suppressor diode D is only necessary for

20 IMX 7 types. To withstand 150 V transients according to

19 Pfl 1, applicable for 40 IMX 7 types, the same external

circuitry with similar components as for IEC/EN 61000-4-5,

level 2 compliance can be used.

¹The built-in overvoltage lockout circuit shuts down the converter

at approx. 38 V protecting the input up to 50 V DC. 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.

Example for external circuitry to comply with

IEC/EN 61000-4-5, level 2 (transzorb D not necessary for

40/70/110 IMX 7 types).

²If transients generating currents above the peak pulse current

are possible then an external limiting network such as the circuit

recommended for IEC/EN 61000-4-5, level 2 compliance is

necessary.

Reverse Polarity Protection at Input

1 A/Div.

04030

The suppressor diode on the input also provides for reverse

polarity protection by conducting current in the reverse di-

rection, thus protecting the unit. An external fuse is required

to limit this current:

– For 20 IMX 7 a fast 2 A (F2A) fuse is recommended.

– For 40 IMX 7 a fast 1 A (F1A) fuse is recommended.

– For 70 IMX 7 a fast 0.63 A (F.63A) fuse is recommended.

– For 110 IMX 7 a fast 0.63 A (F.63A) fuse is recommended.

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.
