The QBE025A0B series provide up to 25A output current in an industry standard quarter brick, which makes it an ideal choice for small space, high current and 12V intermediate bus voltage applications. The converter incorporates synchronous rectification technology and innovative packaging techniques to achieve ultra high efficiency reaching 94% at 12V full load. This leads to lower power dissipation such that for many applications a heat sink is not required. The QBE025A0B series power modules are isolated dc-dc converters that operate over an input voltage range from 42 to 53 Vdc and provide a single regulated 12V output. The output is fully isolated from the input, allowing versatile polarity configurations and grounding connections. Built-in filtering for both input and output minimizes the need for external filtering. This product is affected by a Permanent Injunction entered by the United States District Court for the Eastern District of Texas, Marshall Division in Civil Action No. 2:07-cv-00497-TJW-CE copy enclosed .

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 fastacting fuse with a maximum rating of 15 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.

Although the maximum TH temperature of the power modules is 110 °C - 115 °C, you can limit this temperature to a lower value for extremely high reliability. Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. The thermal derating figures 14-17 show the maximum output current that can be delivered by each module in the respective orientation without exceeding the maximum TH temperature versus local ambient temperature TA for air flows of 1 m/s 200 ft./min and 2m/s 400 ft./min . Note that the natural convection condition was measured at m/s to m/s 10ft./min. to 20 ft./min. however, systems in which these power modules may be used typically generate natural convection airflow rates of m/s 60 ft./min. due to other heat dissipating components in the system. The use of Figures 14 - 15 are shown in the following example: Example What is the minimum airflow necessary for a QBE025A0B operating at VI = 48 V, an output current of 12A, and a maximum ambient temperature of 70 °C in transverse orientation.

Through-Hole Lead-Free Soldering Information The RoHS-compliant through-hole products use the SAC Sn/Ag/Cu Pb-free solder and RoHS-compliant components. They are designed to be processed through single or dual wave soldering machines. The pins have an RoHS-compliant finish that is compatible with both Pb and Pb-free wave soldering processes. A maximum preheat rate of 3C/s is suggested. The wave preheat process should be such that the temperature of the power module board is kept below 210C. For Pb solder, the recommended pot temperature is 260C, while the Pb-free solder pot is 270C max. Not all RoHS-compliant through-hole products can be processed with paste-through-hole Pb or Pb-free reflow process. If additional information is needed, please consult with your Lineage Power representative for more details. Post Solder Cleaning and Drying Considerations Post solder cleaning is usually the final circuit-board assembly process prior to electrical board testing. The result of inadequate cleaning and drying can affect both the reliability of a power module and the testability of the finished circuit-board assembly.
