FUSE CONSIDERATION
The power module is not internally fused. An input line fuse must always be used.
The encapsulated power module can be used in a wide variety of applications, ranging from simple stand-alone operation to an integrated part of
sophisticated power architecture.
To maximum flexibility, internal fusing is not included; however, to achieve maximum safety and system protection, always use an input line fuse. The
input line fuse suggest as below：

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.
Proper cooling can be verified by measuring the point in the figure below.
The temperature at this location should not exceed 110°C.
When operating, adequate cooling must be provided to maintain the test point temperature at or below 110°C.
Although the maximum point temperature of the power modules is 110°C, you can limit this temperature to a lower value for extremely high reliability.
■ Thermal test condition with vertical direction by natural convection (20LFM).

OUTPUT VOLTAGE ADJUSTMENT
Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of the module.
This is accomplished by connecting an external resistor between the Trim pin and either the +Sense or -Sense pins.
With an external resistor between the Trim and -Sense, the output voltage set point increases.
With an external resistor between the Trim and +Sense, the output voltage set point decreases.
The external Trim resistor needs to be at least 1/16W resistors.
EXTERNAL OUTPUT TRIMMING
Output can be externally trimmed by using the method shown below.
