Highly inductive source impedance can affect the stability of the power module. Input external C-L-C filter is recommended to minimize input reflected ripple current. The inductor is simulated source impedance of 12H and capacitor is Nippon Chemi-con KZE series 220F/100V&33F/100V. The capacitor must as close as possible to the input terminals of the power module for lower impedance. Output Over Current Protection When excessive output currents occur in the system, circuit protection is required on all power supplies. Normally, overload current is maintained at approximately about 150 percent of rated current for TON 15-WI single output series. Hiccup-mode is a method of operation in a power supply whose purpose is to protect the power supply from being damaged during an over-current fault condition. It also enables the power supply to restart when the fault is removed. One of the problems resulting from over current is that excessive heat may be generated in power devices; especially MOSFET and Shottky diodes and the temperature of those devices may exceed their specified limits. A protection mechanism has to be used to prevent those power devices from being damaged. Output Over Voltage Protection The output over-voltage protection consists of a Zener diode that monitors the output voltage on the feedback loop. If the voltage on the output terminals exceeds the over-voltage protection threshold, then the Zener diode will send a current signal to the control IC to limiting the output voltage.

This is accomplished by connecting an external resistor between the TRIM pin and either the +Vout or -Vout pins. With an external resistor between the TRIM and -Vout pin, the output voltage set point increases. With an external resistor between the TRIM and +Vout pin, the output voltage set point decreases.

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 120C. When Operating, adequate cooling must be provided to maintain the test point temperature at or below 120C. Although the maximum point Temperature of the power modules is 120C, you can limit this Temperature to a lower value for extremely high reliability.

Safety and Installation Instruction Fusing Consideration Caution: This power module is not internally fused. An input line fuse must be used always. 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 normal-blow fuse with maximum rating of 3A for TON 15-24xxWI modules and 1.5A for TON 15-48xxWI modules. Based on the information provided in this data sheet 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 TON 15-WI SERIES of DC/DC converters has been calculated according to Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40C (Ground fixed and controlled environment ). The resulting figure for MTBF is 1322000 hours. MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25C. The resulting figure for MTBF is 514700 hours.
