Normally, the current limit is maintained at approximately 105~120 percent of rated current for TEP 150WI series. If the output load current is over rating, the output current will keep in a constant value. And the output voltage will fall. All of the TEP 150WI series current limiting supplies are self restoring; that is, when the overload is removed or corrected, the output voltage is automatically restored to the previously set value. Otherwise, if the output resistance is become short, it will operate in hiccup protection. The details are shown below.

Condition: Vout < 4.3V (typ.) to Output Short. (TEP 150-xx12WI, TEP 150-xx13WI) Vout < 8.0V (typ.) to Output Short. (TEP 150-xx15WI, TEP 150-xx16WI) Vout < 13V (typ.) to Output Short. (TEP 150-xx18WI) 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.

If a fault condition occurs, the temperature of the unit will be higher. And it 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 “Shunt Down” 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 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.

Fusing Consideration Caution: This power module is not internally fused. An input line fuse must always be used. This 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 safety agencies require a slow-blow fuse with maximum rating of 30A for TEP 150–24xxWI and 15A for TEP 150–48xxWI. Based on the information provided in this datasheet on Inrush energy and maximum dc input current; the same type of fuse with lower rating can be used. Refer to the fuse manufacturer’s data for further information. MTBF and Reliability The MTBF of TEP 150 series of DC/DC converters has been calculated using Bellcore TR-NWT-000332 Case 1: 50% stress, Operating Temperature at 40°C. The resulting figure for MTBF is 1’525’000 hours. MIL-HDBK 217F Notice2 Full Load, Operating Temperature at 40°C, Air Flow = 400LFM (Ground, Benign, controlled environment ) The resulting figure for MTBF is 135’300 hours.
