2W, Single and Dual Output
Thermal Consideration
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. Proper cooling can be verified by
measuring the point as shown in the figure below. The temperature at this location should not exceed 100°C. During performance, adequate
cooling must be provided to maintain the test point temperature at or below 100°C. Although the maximum point Temperature of the power
modules is 100°C, you can limit the case temperature to a lower value for high reliability.
