Description

Features, Applications

Input to output electric strength test kV DC Input voltage ranges: 8.4...36, 16.8...75 and V DC Single and dual outputs of V DC Extremely wide input voltage ranges Electrical isolation, single and dual outputs Immunity to IEC/EN and -6 High efficiency (typ. 82%) Flex power: flexible load distribution No load and short-circuit proof High reliability and no derating Operating ambient temperature �40...+85 �C Industrial, alternative and SMD pinout DIL 24 case with 8.5 mm profile Safety according to IEC/EN UL 1950 LGA

The IMX 4 series of board mountable 4 W 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 telecommunications where variable input voltages or high transient voltages are prevalent. Covering a total input voltage range from V DC with four different types the units are available with single and dual outputs from 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. The converters are designed and built according to the international safety standards IEC/EN UL 1950, CAN/CSA C22.2 No.950-95 and are LGA and UL marked. 70 IMX 4 types have supplementary insulation and are 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 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 to an ambient temperature �C in free air without using any potting material. Various options as e.g. extended temperature range �40...85 �C, SMD pinout or K-pinout, an alternative to the standard industrial pinout, provide a high level of application specific engineering and design-in flexibility.

For delivery lead times contact factory. Some types require a minimum order quantity.

Examples: 40 IMX 4-0505-8K: DC-DC converter, input voltage range V, 2 outputs providing V, 350 mA, temperature range �40...85 �C, alternative pinout. 20 IMX 4-12-9M: DC-DC converter, input voltage range 8.4...36 V, SMD-pinout, one output providing V, 340 mA. Temperature range �40...71 �C.

The IMX 4 DC-DC modules are feedback controlled flyback converters using current mode PWM (Pulse Width Modulation). The converter input is protected against transients by means of a suppressor diode. The output voltage is monitored by a separate transformer winding close to the secondary windings and fed back to the control circuit.

Current limitation is provided by the primary circuit, thus limiting the total output current (Io nom for the single and Io1 nom + Io2 nom for the dual output types). The close magnetic coupling provided by the planar construction ensures very good regulation and allows for flexible load distribution on dual output types.
