Description
The IMX4 Series of board-mountable, 4-watt DC-DC
converters has been designed according to the latest industry
requirements and standards. The converters are particularly
suitable for use in mobile or stationary applications in
transport, industry, or telecom, where variable input voltages or
high transient voltages are prevalent.
Covering a total input voltage range from 8.4 VDC up to
121 VDC with three different models, the converters are
available with single and dual outputs from 3.3 up to ±24 VDC
with flexible load distribution. Features include efficient input
and output filtering with unsurpassed transient and surge
protection, low output ripple and noise, consistently high
efficiency over the entire input voltage range and high
reliability as well as excellent dynamic response to load and
line changes.
The converters exhibit basic insulation and are designed and
built according to the international safety standards IEC/EN
1 _{except 70IMX4}
2 _{70IMX4 models}
60950-1 2^nd Ed. 70IMX4 models are CE-marked.
A special feature is their small case size, DIL 24 with only
8.5 mm profile. The circuit is comprised of integrated planar
magnetics, and all components are automatically assembled
and solidly soldered onto a single PCB without any wire
connection. Thanks to the rigid mechanical design, the
converters withstand an extremely high level of shock and
vibrations. Careful considerations of possible thermal stresses
ensure the absence of hot spots providing long life in
environments where temperature cycles are a reality. The
thermal design allows operation at full load up to an ambient
temperature of 85 °C in free air without using any potting
material.
Several options, such as open-frame or an alternative
industrial pinout, provide a high level of application-specific
engineering and design-in flexibility.
