IMX4 Series Data Sheet 4 Watt DC-DC Converters Features RoHS lead-free-solder and lead-solder-exempted products are available. 5 year warranty for RoHS lead-free-solder products with temperature index -8. Input voltage ranges up to 121 VDC 8.5 Voltage withstand test 1500 VAC 0.34 20 32 1 or 2 isolated outputs up to 48 V 0.8 1.25 Extremely wide input voltage ranges Immunity according to IEC/EN 61000-4-2, -3, -4, -5, -6 High efficiency (typ. 83%) Flexible load distribution on outputs Outputs no-load, overload, and short-circuit proof High reliability Operating ambient temperature 40 to +85 C Thermal protection Industrial and alternative pinout DIL 24 case with 8.5 mm profile Safety-approved to the latest edition of IEC/EN 60950-1 and UL/CSA 60950-1 Description 1 The IMX4 Series of board-mountable 4-watt DC-DC con- verters has been designed according to the latest industry 1 70IMX4 models requirements and standards. The converters are particularly suitable for use in mobile or stationary applications in trans- A special feature is their small case size, DIL 24 with only port, industry, or telecom, where variable input voltages or high 8.5 mm profile. The circuit is comprised of integrated planar transient voltages are prevalent. magnetics, and all components are automatically assembled Covering a total input voltage range from 8.4VDC up to and solidly soldered onto a single PCB without any wire 121VDC with three different models, the converters are connection. Thanks to the rigid mechanical design, the available with single or dual output from 3.3 up to 24 VDC converters withstand an extremely high level of shock and with flexible load distribution. Features include efficient input vibrations. Careful consideration of possible thermal stresses and output filtering with unsurpassed transient and surge ensure the absence of hot spots providing long life in protection, low output ripple and noise, consistently high environments where temperature cycles are a reality. The efficiency over the entire input voltage range and high thermal design allows operation at full load up to an ambient reliability as well as excellent dynamic response to load and temperature of 85 C in free air without using any potting line changes. material. The converters exhibit basic insulation and are designed and Several options, such as open-frame or an alternative industrial built according to the international safety standards IEC/EN pinout, provide a high level of application-specific engineering 60950-1. 70IMX4 models are CE-marked. and design-in flexibility.
