The FW250F1 and FW300F1 Power Modules are dc-dc converters that operate over an input voltage range of 36 Vdc to 75 Vdc and provide a precisely regulated dc output. The outputs are fully isolated from the inputs, allowing versatile polarity configurations and grounding connections. The modules have maximum power ratings from 250 W to 300 W at a typical full-load efficiency of

Two or more modules may be paralleled with forced load sharing for redundant or enhanced power applications. The package, which mounts on a printed-circuit board, accommodates a heat sink for high-temperature applications.

Absolute Maximum Ratings

Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those given in the operations sections of the data sheet. Exposure to absolute maximum ratings for extended periods can adversely affect device reliability.

Fusing Considerations

CAUTION This power module is not internally fused. An input line fuse must always be used.

This encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of a sophisticated power architecture. To preserve maximum flexibility, internal fusing is not included however, to achieve maximum safety and system protection, always use an input line fuse. The safety agencies require a normal-blow, dc fuse with a maximum rating of 20 A see Safety Considerations section . Based on the information provided in this data sheet on inrush energy and maximum dc input current, the same type of fuse with a lower rating can be used. Refer to the fuse manufacturer’s data for further information.
The temperature at this location should not exceed 100 °C. The maximum case temperature can be limited to a lower value for extremely high reliability. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table.

For additional information about these modules, refer to the Thermal Management for FC- and FW-Series 250 W Board-Mounted Power Modules Technical Note TN96-009EPS .

Heat Transfer Without Heat Sinks

Derating curves for forced-air cooling without a heat sink are shown in Figures 25 and These curves can be used to determine the appropriate airflow for a given set of operating conditions. For example, if the unit with airflow along its length dissipates 20 W of heat, the correct airflow in a 40 °C environment is m/s 200 ft./min. .

Heat Transfer with Heat Sinks

The power modules have through-threaded, M3 x mounting holes, which enable heat sinks or cold plates to be attached to the module. The mounting torque must not exceed N-m 5 in.-lb. . For the screw attachment from the pin side, the recommended hole size on the customer’s PWB around the mounting holes is ± inches. If a larger hole is used, the mounting torque from the pin side must not exceed N-m in.-lbs. .

Thermal derating with heat sinks is expressed by using the overall thermal resistance of the module. Total module thermal resistance is defined as the maximum case temperature rise max divided by the module power dissipation PD :

The location to measure case temperature TC is shown in Figure Case-to-ambient thermal resistance vs. airflow for various heat sink configurations is shown in Figure 27 and Figure These curves were obtained by experimental testing of heat sinks, which are offered in the product catalog.
