The 25 W dual output power modules are designed to
operate in a variety of thermal environments. As with
any electronic component, sufcient cooling must be
provided to help ensure reliable operation of the unit.
Heat-dissipating components inside the module are
thermally coupled to the case. Heat is removed by con-
duction, convection, 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 15 was used to collect data. Actual performance
can vary depending on the particular application
environment.
