100W Single 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.
Output Over Voltage Protection
The output over-voltage protection consists of circuitry that monitors the voltage on the output terminals. If the voltage on the
output terminals exceeds the over-voltage protection threshold, then the module enter the non-latch hiccup mode.
Over Temperature Protection
Sufficient cooling is needed for the power module and provides more reliable operation of the unit. If a fault condition occurs, the
temperature of the unit will be higher. And will damage the unit. For protecting the power module, the unit includes
over-temperature protection circuit. When the temperature of the case is to the protection threshold, the unit enters “Hiccup”
mode. And it will auto restart when the temperature is down.
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.
