Data Sheet March 27, 2008 QW010/015/020-H Series Power Modules with Baseplate; 36 – 75Vdc Input, 1.0 - 5.0Vdc Output; 10A to 20A Output Current Description The QW-H series dc-dc converters are same as QW series with baseplate mounted on topside, which accommodate for standard quarter brick heatsink attachment. The QW-H series allow customer to operate the module in an extreme thermal environment with attachment of heatsink/cold-plate for proper cooling of internal component to heighten reliable and consistent operation. For additional technical data, consult QW010/0150/020 series data sheet.

The baseplate includes quarter brick through-threaded, M3 x 0.5 mounting hole pattern, which enable heat sinks or cold plates to attach to the module. The mounting torque must not exceed 0.56 N-m (5 in.lb.) during heat sink assembly. This module operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation. Considerations include ambient temperature, airflow, module power dissipation, and the need for increased reliability. A reduction in the operating temperature of the module will result in an increase in reliability. The thermal data presented here is based on physical measurements taken in a wind tunnel. Heat-dissipating components are mounted on the topside of the module and coupled to the baseplate with thermal gap material. Heat is removed by conduction, convection and radiation to the surrounding environment. The thermal reference point, Tref . used for the derating curves is shown in Figure 1. For reliable operation Tref . temperature should not exceed 118°C. The output power of the module should not exceed the rated power for the module as listed in the Ordering Information table. Although the maximum Tref temperature of the power modules is 118°C, users can limit this temperature to a lower value for extremely high reliability. Please refer to the Application Note “Thermal Characterization Process For Open-Frame BoardMounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures. LINEAGE POWER Tref AirFlow Figure 1. Tref Temperature Measurement Location Heat Transfer via Convection Increased airflow over the module enhances the heat transfer via convection. Following derating figures shows the maximum output current that can be delivered by each module in the respective orientation without exceeding the maximum Tref temperature versus local ambient temperature (TA) for natural convection through 1m/s (200 ft./min). Note that the natural convection condition was measured at 0.05 m/s to 0.1 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 0.3 m/s (60 ft./min.) due to other heat dissipating components in the system. 3 QW010/015/020 Series Brick Power Modules: 36 - 75Vdc Input; 1.0Vdc to 5Vdc Output; 10A to 20A Output current Data Sheet March 27, 2008 Thermal considerations (continued) 12 OUTPUT CURRENT, IO (A) 10 8 6 4 200 LFM 2 100 LFM NC 0 20 30 40 50 60 70 80 90 LOCAL AMBIENT TEMPERATURE, TA (°C) Figure 2.
