20W Single & Dual Output
Short Circuitry Protection
Continuous, hiccup and auto-recovery mode.
During short circuit, converter still shut down. The average current during this condition will be very low and the device can be
safety in this condition.
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 the figure below. The temperature at this location should not exceed 105°C.
When operating, adequate cooling must be provided to maintain the test point temperature at or below 105°C. Although the
maximum point temperature of the power modules is 105°C, you can limit this Temperature to a lower value for extremely high
reliability.
Heat Sink Consideration
Equip heat sink for lower temperature and higher reliability of the module. Considering space and air-flow is the way to choose
which heat sink is needed.
There are two types for choosing
Suffix –HC: Heat Sink mounted with Clamp Suffix –HS: Heat Sink
All dimensions in millimeters
