B 09/03/08 Page 10 Technical Specification BASICOPERATIONANDFEATURES TheMQFLdc-dcconverterusesatwo-stagepowerconversion topology. The first, or regulation, stage is a buck-converter that keeps the output voltage constant over variations in line, load, and temperature. The second, or isolation, stage uses transformers to provide the functions of input/output isolation and voltage transformation to achieve the output voltage required. Inthedualoutputconvertertherearetwosecondarywindings in the transformer of the isolation stage, one for each output. There is only one regulation stage, however, and it is used to control the positive output. The negative output therefore displays "Cross-Regulation", meaning that its output voltage depends on how much current is drawn from each output. Both the positive and the negative outputs share a common OUTPUTRETURNpin. Boththeregulationandtheisolationstagesswitchatafixed frequency for predictable EMI performance. The isolation stage switches at one half the frequency of the regulation stage, but due to the push-pull nature of this stage it creates a ripple at double its switching frequency. As a result, both the input and the output of the converter have a fundamental ripplefrequencyofabout550kHzinthefree-runningmode. Rectification of the isolation stage's output is accomplished with synchronous rectifiers. These devices, which are MOSFETswithaverylowresistance,dissipatefarlessenergy than would Schottky diodes. This is the primary reason why theMQFLconvertershavesuchhighefficiency,particularlyat low output voltages. Besidesimprovingefficiency,thesynchronousrectifierspermit operation down to zero load current. There is no longer a need for a minimum load, as is typical for converters that use diodes for rectification. The synchronous rectifiers actually permit a negative load current to flow back into the converter's output terminals if the load is a source of short or long termenergy.TheMQFLconvertersemploya"back-drivecurrentlimit"tokeepthisnegativeoutputterminalcurrentsmall. There is a control circuit on both the input and output sides of theMQFLconverterthatdeterminestheconductionstateofthe power switches. These circuits communicate with each other across the isolation barrier through a magnetically coupled device. No opto-isolators are used. A separate bias supply provides power to both the input and output control circuits. An input under-voltage lockout feature with hysteresis is provided, as well as an input over-voltage shutdown. There is also an output current limit that is nearly constant as the load impedancedecreasestoashortcircuit(i.e.,thereisnofold- MQFL-28-05D Output: 5 V Current: 24 A Total back or fold-forward characteristic to the output current under this condition). When a load fault is removed, the output voltage rises exponentially to its nominal value without an overshoot. The MQFL converter's control circuit does not implement an output over-voltage limit or an over-temperature shutdown. The following sections describe the use and operation of additionalcontrolfeaturesprovidedbytheMQFLconverter. CONTROLFEATURES ENABLE: The MQFL converter has two enable pins. Both must have a logic high level for the converter to be enabled. A logic low on either pin will inhibit the converter. The ENA1 pin (pin 4) is referenced with respect to the converter'sinputreturn(pin2).TheENA2pin(pin12)isreferenced with respect to the converter's output return (pin 8). This permits the converter to be inhibited from either the input or the output side. Regardless of which pin is used to inhibit the converter, the regulationandtheisolationstagesareturnedoff.However, whentheconverterisinhibitedthroughtheENA1pin,thebias supply is also turned off, whereas this supply remains on when the converter is inhibited through the ENA2 pin. A higher input standby current therefore results in the latter case. Both enable pins are internally pulled high so that an open connectiononbothpinswillenabletheconverter.FigureA showstheequivalentcircuitlookingintoeitherenablepins.It isTTLcompatible. 5.6V PIN 4 (or PIN 12) 1N4148 ENABLE 82K TO ENABLE CIRCUITRY 2N3904 125K 250K PIN 2 (or PIN 8) IN RTN Figure A: Equivalent circuit looking into either the ENA1 or ENA2 pins with respect to its corresponding return pin.

As such, the share pin cannot cause two or more paralleled converters to share load currents on the positive or negative outputs independently.

INPUT UNDER-VOLTAGE LOCKOUT: The MQFL converter has an under-voltage lockout feature that ensures the converter will be off if the input voltage is too low. The threshold of input voltage at which the converter will turn on is higher that the thresholdatwhichitwillturnoff.Inaddition,theMQFLconverterwill not respond to a state of the input voltage unless it has remained inthatstateformorethanabout200s.

If the VINinputisbroughtdowntonearly0Vandbackintotheoperating range, there is no startup inhibit, and the output voltage will riseaccordingtothe"Turn-OnDelay,RisingVin"specification. BACK-DRIVE CURRENT LIMIT: Converters that use MOSFETsassynchronousrectifiersarecapableofdrawing a negative current from the load if the load is a source of short- or long-term energy. This negative current is referred toasa"back-drivecurrent". Conditions where back-drive current might occur include paralleled converters that do not employ current sharing, or where the current share feature does not adequately ensure sharing during the startup or shutdown transitions. It can also occur when converters having different output voltages are connected together through either explicit or parasitic diodes that, while normally off, become conductive during startup or shutdown. Finally, some loads, such as motors, canreturnenergytotheirpowerrail.Evenaloadcapacitor is a source of back-drive energy for some period of time during a shutdown transient. To avoid any problems that might arise due to back-drive current, the MQFL converters limit the negative current that the converter can draw from its output terminals. The threshold for this back-drive current limit is placed sufficiently below zero so that the converter may operate properly downtozeroload,butitsabsolutevalue(seetheElectrical Characteristics page) is small compared to the converter's rated output current. MQFL-28-05D Output: 5 V Current: 24 A Total INPUT SYSTEM INSTABILITY: This condition can occur because any dc-dc converter appears incrementally as a negative resistance load. A detailed application note titled "Input System Instability" is available on the SynQor website which provides an understanding of why this instability arises, and shows the preferred solution for correcting it. THERMAL CONSIDERATIONS: Figure 11 shows the suggestedPowerDeratingCurvesforthisconverterasafunctionof thecasetemperatureandthemaximumdesiredpowerMOSFET junction temperature. All other components within the converter are cooler than its hottest MOSFET, which at full power is no morethan20Chigherthanthecasetemperaturedirectlybelow thisMOSFET. TheMil-HDBK-1547Acomponentderatingguidelinecallsfora maximum component temperature of 105C. Figure 11 therefore has one power derating curve that ensures this limit is maintained.IthasbeenSynQor'sextensiveexperiencethatreliable long-term converter operation can be achieved with a maximum componenttemperatureof125C.Inextremecases,amaximum temperatureof145Cispermissible,butnotrecommendedfor long-term operation where high reliability is required. Derating curves for these higher temperature limits are also included in Figure 11. The maximum case temperature at which the convertershouldbeoperatedis135C. When the converter is mounted on a metal plate, the plate will help to make the converter's case bottom a uniform temperature. How well it does so depends on the thickness of the plate and on the thermal conductance of the interface layer (e.g. thermal grease,thermalpad,etc.)betweenthecaseandtheplate.Unless this is done very well, it is important not to mistake the plate's temperature for the maximum case temperature. It is easy for themtobeasmuchas5-10Cdifferentatfullpowerandathigh temperatures. It is suggested that a thermocouple be attached directly to the converter's case through a small hole in the plate when investigating how hot the converter is getting. Care must also be made to ensure that there is not a large thermal resistance between the thermocouple and the case due to whatever adhesive might be used to hold the thermocouple in place.
