The 25 W triple output power modules are designed to

operate in a variety of thermal environments. As with

any electronic component, sufficient cooling must be

provided to ensure reliable operation. Heat dissipating

components inside the module are thermally coupled

to the case to enable heat removal by conduction, con-

vection, and radiation to the surrounding environment.

The thermal data presented is based on measure-

ments taken in a wind tunnel. The test setup shown in

Figure 22 was used to collect data. Actual performance

can vary depending on the particular application

environment.
