Normally, overload current is maintained at approximately 118~142 percent of rated current for FEC30-W. 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. There are other ways of protecting the power supply when it is over-loaded, such as the maximum current limiting or current foldback methods. One of the problems resulting from over current is that excessive heat may be generated in power devices, especially MOSFET and Schottky diodes and the 5/29 Power Mate Technology Data Sheet February 2003 temperature of those devices may exceed their specified limits. A protection mechanism has to be used to prevent those power devices from being damaged. The operation of hiccup is as follows. When the current sense circuit sees an over-current event, the controller shuts off the power supply for a given time and then tries to start up the power supply again. If the over-load condition has been removed, the power supply will start up and operate normally; otherwise, the controller will see another over-current event and shut off the power supply again, repeating the previous cycle. Hiccup operation has none of the drawbacks of the other two protection methods, although its circuit is more complicated because it requires a timing circuit. The excess heat due to overload lasts for only a short duration in the hiccup cycle, hence the junction temperature of the power devices is much lower. The hiccup operation can be done in various ways. For example, one can start hiccup operation any time an over-current event is detected; or prohibit hiccup during a designated start-up is usually larger than during normal operation and it is easier for an over-current event is detected; or prohibit hiccup during a designated start-up interval(usually a few milliseconds). The reason for the latter operation is that during start-up, the power supply needs to provide extra current to charge up the output capacitor. Thus the current demand during start-up is usually larger than during normal operation and it is easier for an over-current event to occur. If the power supply starts to hiccup once there is an over-current, it might never start up successfully. Hiccup mode protection will give the best protection for a power supply against over current situations, since it will limit the average current to the load at a low level, so reducing power dissipation and case temperature in the power devices. 6/29 Power Mate Technology Data Sheet February 2003 Under voltage shoutdown Input Power status Voltage 24 V DC/DC ON 10VDC DC/DC OFF 8VDC DC/DC ON 18VDC DC/DC OFF 16VDC 48V Remote On/Off Control Two remote on/off control are available for FEC30W. Positive logic remote on/off turns the module on during a logic-high voltage on the remote on/off pin, and off during a logic low. Negative logic remote on/off turns the module of during a logic high and on during a logic low or when the remote on/off pin is shorted to the Vi(-) pin. The FEC30W series used a positive logic remote on/off as standard module. For the negative logic ON/OFF control add the suffix：" N ". Ex: FEC30-24S05WN. To turn the power module on and off, the user must supply a switch to control the voltage between the on/off terminal(Von/off)and the Vi(-). The switch may be an open collector or equivalent(see figure). A logic low is Von/off = 0V to 1.2V. The maximum Ion/off during a logic low is 20uA. The switch should maintain a logic-low voltage while sinking 20uA. During a logic high, the maximum Von/off generated by the power module is 12V. The maximum allowable leakage current of the switch at Von/off = 12V is 40uA. The module has internal capacitance to reduce noise at the on/off pin. Additional capacitance is not generally needed and may degrade the start-up characteristics of the module. Figure A details five possible circuits for driving the ON/OFF Pin.

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. External trim adjustment Output voltage set point adjustment allows the user to increase or decrease the output voltage set point of a module. This is accomplished by connecting an external resistor between the TRIM pin and either the Vo(+) or Vo(-) pins. With an external resistor between the TRIM and Vo(+) pin, the output voltage set point decreases. With an external resistor between the TRIM and Vo(-) pin, the output voltage set point increases. 1 +Input 2 -Input 1 +Input 2 -Input +Output 6 -Output 7 Trim 8 +Output -Output Trim Rd Trim up Ru 6 7 8 EXTERNAL OUTPUT TRIMMING 8/29 Trim down Power Mate Technology Data Sheet February 2003 TRIM TABLE FEC30-XXS1P5W Trim up 1 Vout= 1.485 Ru= 3 4 5 1.47 1.455 1.44 6 7 8 1.425 1.41 1.395 9 10 % 1.38 1.365 1.35 Volts 5.7029 2.5708 1.5267 1.0047 0.6915 0.4827 0.3335 0.2216 0.1346 0.0650 KOhms Trim down 1 Vout= 1.515 Rd= 2 2 3 4 5 1.53 1.545 1.56 6 7 8 1.575 1.59 1.605 9 10 % 1.62 1.635 1.65 Volts 4.5742 2.0628 1.2257 0.8072 0.5560 0.3886 0.2690 0.1793 0.1096 0.0537 KOhms FEC30-XXS1P8W Trim up 1 Vout= 1.818 Ru= 3 4 5 1.836 1.854 1.872 6 1.89 7 8 9 10 1.908 1.926 1.944 1.962 % 1.98 Volts 11.8754 5.2640 3.0866 2.0028 1.3540 0.9222 0.6140 0.3831 0.2036 0.0600 KOhms Trim down 1 Vout= 1.782 Rd= 2 2 3 4 5 1.764 1.746 1.728 6 1.71 7 8 9 10 1.692 1.674 1.656 1.638 % 1.62 Volts 14.3796 6.5002 3.8426 2.5079 1.7052 1.1693 0.7861 0.4985 0.2747 0.0956 KOhms FEC30-XXS2P5W Trim up 1 2 3 4 5 6 7 8 9 Vout= 2.525 2.55 2.575 2.6 2.625 2.65 2.675 2.7 2.725 Ru= 2.75 Volts 36.6531 16.5674 9.8260 6.4466 4.4162 3.0614 2.0931 1.3666 0.8013 0.3490 KOhms Trim down 1 2 3 4 5 6 7 8 9 Vout= 2.475 2.45 2.425 2.4 2.375 2.35 2.325 2.3 2.275 Rd= 10 10 % 2.25 Volts 50.2041 22.6201 13.4892 8.9356 6.2073 4.3900 3.0926 2.1201 1.3639 0.7591 KOhms FEC30-XXS3P3W Trim up 1 2 3 4 Vout= 3.333 3.366 3.399 3.432 Ru= 6 7 8 9 10 % 3.465 3.498 3.531 3.564 3.597 3.63 Volts 57.9599 26.1726 15.5801 10.2844 7.1073 4.9892 3.4764 2.3418 1.4593 0.7533 KOhms Trim down 1 2 3 4 Vout= 3.267 3.234 3.201 3.168 Rd= 5 5 6 7 8 9 10 % 3.135 3.102 3.069 3.036 3.003 2.97 Volts 69.4348 31.2263 18.4861 12.1153 8.2926 5.7441 3.9236 2.5582 1.4963 0.6467 KOhms 9/29 Power Mate Technology Data Sheet February 2003 FEC30-XXS05W Trim up 1 2 3 4 5 6 7 8 9 Vout= 5.05 5.1 5.15 5.2 5.25 5.3 5.35 5.4 5.45 Ru= 10 5.5 Volts 43.2232 18.1319 10.5959 6.9661 4.8305 3.4240 2.4276 1.6848 1.1097 0.6512 KOhms Trim down 1 2 3 4 5 6 7 8 9 Vout= 4.95 4.9 4.85 4.8 4.75 4.7 4.65 4.6 4.55 Rd= % 10 % 4.5 Volts 39.4177 18.9991 11.5799 7.7436 5.3996 3.8189 2.6809 1.8225 1.1519 0.6135 KOhms FEC30-XXS12W Trim up 1 2 3 4 5 6 7 8 9 Vout= 12.12 12.24 12.36 12.48 12.6 12.72 12.84 12.96 13.08 Ru= 13.2 Volts 1019.4475 257.4148 134.3919 84.0552 56.6768 39.4668 27.6475 19.0290 12.4663 7.3021 KOhms Trim down 1 2 3 4 5 6 7 8 9 Vout= 11.88 11.76 11.64 11.52 11.4 11.28 11.16 11.04 10.92 Rd= 10 10 % 10.8 Volts 270.2050 149.6275 95.7604 65.2378 45.5871 31.8777 21.7690 14.0070 7.8596 2.8704 KOhms FEC30-XXS15W Trim up 1 2 3 4 5 6 7 8 9 Vout= 15.15 15.3 15.45 15.6 15.75 15.9 16.05 16.2 16.35 Ru= % 16.5 Volts 455.6690 192.8897 111.4831 71.8484 48.3988 32.9014 21.8975 13.6802 7.3099 2.2269 KΩ Trim down 1 2 3 4 5 6 7 8 9 Vout= 14.85 14.7 14.55 14.4 14.25 14.1 13.95 13.8 13.65 Rd= 10 10 % 13.5 Volts 449.0121 210.2234 125.3763 81.8946 55.4567 37.6837 24.9156 15.2991 7.7956 1.7777 KΩ 10/29 Power Mate Technology Data Sheet February 2003 Thermal Consideration The power module operates in a variety of thermal environments; however, sufficient cooling should be provided to POWER MATE TECHNOLOGY CO., help ensure reliable operation of the unit. Heat is removed by conduction, convention, and radiation to the surrounding environment. Proper cooling can be verified by measuring the case ●Ctrl Tri m● ● － Vi － Vo● ● + V i OUT:xxVDC xxxmA + Vo ● temperature. The case temperature (Tc) should be measured at the FEC30-xxSxxW position indicated in right figure. The temperature at this location should not exceed 100℃. When operating the power module, adequate cooling must be provided to maintain the power module case temperature at or below 100℃. Although the maximum case temperature of the power modules is 100℃, you can limit this temperature to a lower value for extremely high reliability. Optimum cooling is obtained with forced convention. Some typical thermal resistance numbers are tabulated below: Thermal resistance vs. air flow chart Air flow rate Typical θca Natural Convention 12.9℃/W 100LFM 10.56℃/W 200LFM 8.22℃/W 300LFM 6.69℃/W 400LFM 5.09℃/W 500LFM 4.86℃/W These numbers are typical only.

Position them with proper intervals to allow enough air ventilation. Ambient temperature around each power supply should not exceed the temperature range shown in de-rating curve. Avoid placing the DC input line pattern layout underneath the unit because it will increase the line conducted noise. Make sure to leave an ample distance between the line pattern layout and the unit. Also, Avoid placing the DC output line pattern layout underneath the unit because it may increase the output noise. Lay out the pattern away from the unit. ＋ ○＋ ○ ○ ○－ －○ × 27/29 Power Mate Technology Data Sheet February 2003 Mechanical Data Dimensions are in millimeters and (inches) Tolerances: x.x mm ± 0.5mm (x.xx in. ± 0.02 in.) x.xx mm ± 0.4mm (x.xxx in. ± 0.015 in.)

The input to output resistance is greater than 109 megohms. Nevertheless, if the system using the power module needs to receive safety agency approval, certain rules must be followed in the design of the system using the model. In particular, all of the creepage and clearance requirements of the end-use safety requirement must be observed. These documents include UL-1950, EN60950 and CSA 22.2-960, although specific applications may have other or additional requirements. 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 a 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 5 A. 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. Minimum Load FEC30W Series does not need the minimum load when applied. MTBF and Reliability The MTBF of FEC30W series of DC/DC converters has been calculated using 1. MIL-HDBK-217F under the following conditions: Nominal Input Voltage Io = Io, max Ta = 25℃ The resulting figure for MTBF is 3.456× 105 hours. 2. Bellcore TR-NWT-000332 Case I: 50% stress, Operating Temperature at 40 ℃ (Ground fixed and controlled environment) The resulting figure for MTBF is 1.315× 106 hours. 29/29
