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 12µH and capacitor is Nippon Chemi-con KZE series 220µF/100V&33µF/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. l Trim up equation l Trim down equation l Trim constants Module G H K L TON 15-xx10WI 5110 2050 0.8 2.5 TON 15-xx11WI 5110 2050 2.5 2.5 TON 15-xx12WI 10000 5110 9.5 2.5 TON 15-xx13WI 10000 5110 12.5 2.5 TRIM TABLE Trim up (%) VOUT (Volts) = RT1 (KΩ) = Trim down (%) VOUT (Volts) = RT2 (KΩ) = Trim up (%) VOUT (Volts) = RT1 (KΩ) = Trim down (%) VOUT (Volts) = RT2 (KΩ) = 1 2 3.333 3.366 385.071 191.511 1 2 3.267 3.234 116.719 54.779 TON 15-xx10WI 3 4 5 3.399 3.432 3.465 126.990 94.730 75.374 3 4 5 3.201 3.168 3.135 34.133 23.810 17.616 6 3.498 62.470 6 3.102 13.486 7 3.531 53.253 7 3.069 10.537 8 3.564 46.340 8 3.036 8.325 9 3.597 40.963 9 3.003 6.604 10 3.630 36.662 10 2.970 5.228 1 2 5.050 5.100 253.450 125.700 1 2 4.950 4.900 248.340 120.590 3 5.150 83.117 3 4.850 78.007 TON 15-xx11WI 4 5 5.200 5.250 61.825 49.050 4 5 4.800 4.750 56.715 43.940 6 5.300 40.533 6 4.700 35.423 7 5.350 34.450 7 4.650 29.340 8 5.400 29.888 8 4.600 24.778 9 5.450 26.339 9 4.550 21.229 10 5.500 23.500 10 4.500 18.390 6 12.720 29.612 6 11.280 116.834 7 12.840 24.652 7 11.160 97.985 8 12.960 20.932 8 11.040 83.848 9 13.080 18.038 9 10.920 72.853 10 13.200 15.723 10 10.800 64.057 6 15.900 22.668 6 14.100 123.779 7 16.050 18.700 7 13.950 103.938 8 16.200 15.723 8 13.800 89.057 9 16.350 13.409 9 13.650 77.483 10 16.500 11.557 10 13.500 68.223 Trim up (%) VOUT (Volts) = RT1 (KΩ) = Trim down (%) VOUT (Volts) = RT2 (KΩ) = 1 2 12.120 12.240 203.223 99.057 1 2 11.880 11.760 776.557 380.723 3 12.360 64.334 3 11.640 248.779 TON 15-xx12WI 4 5 12.480 12.600 46.973 36.557 4 5 11.520 11.400 182.807 143.223 Trim up (%) VOUT (Volts) = RT1 (KΩ) = Trim down (%) VOUT (Volts) = RT2 (KΩ) = 1 2 15.150 15.300 161.557 78.223 1 2 14.850 14.700 818.223 401.557 3 15.450 50.446 3 14.550 262.668 TON 15-xx13WI 4 5 15.600 15.750 36.557 28.223 4 5 14.400 14.250 193.223 151.557 Created by Traco Electronic AG Arp. www.tracopower.com Date: June 23rd, 2008 / Rev.: 1.1 / Page 25 / 32 Application Note 15W 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. 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 120°C. When Operating, adequate cooling must be provided to maintain the test point temperature at or below 120°C. Although the maximum point Temperature of the power modules is 120°C, you can limit this Temperature to a lower value for extremely high reliability.

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 40°C (Ground fixed and controlled environment ). The resulting figure for MTBF is 1´322´000 hours. MIL-HDBK 217F NOTICE2 FULL LOAD, Operating Temperature at 25°C. The resulting figure for MTBF is 514´700 hours.
