IMX7/IMS7 DC-DC Series Data Sheet

7-Watt DC-DC Converters

Electromagnetic Emissions

typically occur in many installations, but especially in battery-

driven mobile applications.

Electromagnetic Compatibility (EMC)

A suppressor diode together with an input filter form an

effective protection against high input transient voltages, which
