Description
mechanical design the units 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.
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 V DC up to 121 V DC
with three different types the units are available with single and dual
outputs from 3.3 up to 24 V DC with flexible load distribution on
dual outputs. 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, high reliability as well as excellent dynamic response to load
and line changes.
Various options as e.g., extended temperature range
–40 to 85°C, or K-pinout, an alternative to the standard
industrial pinout, provide a high level of application specific
engineering and design-in flexibility.
The converters exhibit basic insulation and are designed and built
according to the international safety standards IEC/EN 60950, UL
1950, CAN/CSA C22.2 No.950-95 and are LGA and UL marked.
70IMX4 types have are also CE marked.
A special feature is their small case size, DIL 24 with only 8.5 mm
profile. The circuit comprises integrated planar magnetics and all
components are automatically assembled and solidly soldered
onto a single PCB without any wire connections. Thanks to the rigid
