International Way Milwaukie, Oregon 97222 1-971-206-2800 Page 2 Volant NEA/NEF010 Series Non-Isolated 10A SIP DC/DC Converters Thermal Considerations The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to help ensure reliable operation of the unit. Heat is removed by conduction, convection, and radiation to the surrounding environment. The thermal data presented is based on measurements taken in a set-up as shown in fig 1. when the airflow is parallel to the long axis of the module. The de-rating applies accordingly. The temperature at either location should not exceed 110 C. The output power of the module should not exceed the rated power for the module (VO, set x IO, max). Figure 1: Thermal Measurement Setup Convection Requirements for Cooling To predict the approximate cooling needed for the module, refer to the Power Derating Curve in Figure 2 to Figure 9. These derating curve are approximations of the ambient temperature and airflow required to keep the power module temperature below it's maximum rating. Once the module is assembled in the actual system, the module's temperature should be verified. Proper cooling can be verified by measuring the power module's temperature at Q1-pin 6 and Q2-pin 6 as shown in Figure 1. 1150 Eglinton Avenue East Toronto, Ontario M3C 1H7 1-866-740-1232 NEA/NEF10 6200500000 A04 Nov 15, 2004 www.cdtechno-cps.com 4607 S.E.
