DC-DC Converters PCB Mount Type MG15, MG30, MG40, MG80 Instruction Manual10 Note to use±5V outputPoint A (Center of the Case)+Vin+VoutRLOAD 100%COMRLOAD 0-5%-Vin-VoutFig.11.2 Temperature measuring point (Top View)Fig.10.1 Example of decreasing the fl uctuation of output voltage.!If an output current is 0% to 5% of the rated current, the output isinfl uenced by the other output load condition.20% output voltage fl uctuation may occer.To avoid the fl uctuation, external bleeding resister is required todraw suffi cient current.11 Lifetime expectancy depends onstress by temperature difference!The warranty period is basically 10 years, however it depends onthe lifetime expectancy which is shown in Fig.11.1 if it is less than10 years.11.2 MG30 / MGF30 Lifetime expectancy depends onstress by temperature difference!Product lifetime expectancy depends on case temperature difference( Tc) and number of cycling in a day is shown in Fig.11.3 (Itis calculated based on our accelerated process test result.)If case temperature changes frequently by changing output loadfactor etc., the above the lifetime expectancy design should beapplied as well. And point A which is shown in Fig.11.4 must keepbelow 110C.!Regarding lifetime expectancy design of solder joint, followingcontents must be considered.It must be careful that the soldering joint is stressed by temperaturerise and down which is occurred by self-heating and ambienttemperature change.The stress is accelerated by thermal-cycling, therefore the temperaturedifference should be minimized as much as possible iftemperature rise and down is occurred frequently.11.1 MG15 / MGF15 Lifetime expectancy depends onstress by temperature differenceLifetime expectancy [years]15101time ON/OFF/1day52times ON/OFF/1day3times ON/OFF/1day4times ON/OFF/1day5times ON/OFF/1day030 35 40 45 50 55 60 65 70 75 80 85Rise/fall temperature difference at point ATc [C]!Product lifetime expectancy depends on case temperature difference( Tc) and number of cycling in a day is shown in Fig.11.1 (Itis calculated based on our accelerated process test result.)If case temperature changes frequently by changing output loadfactor etc., the above the lifetime expectancy design should beapplied as well.
