C 12/10/08 Page 21 Technical Specification IQ72-QTC Family BASICOPERATIONANDFEATURES This converter series uses a two-stage power conversion topology. The first stage is a buck-converter that keeps the output voltage constant over variations in line, load, and temperature. The second stage uses a transformer to provide the functions of input/output isolation and voltage step-up or step-downtoachievetheoutputvoltagerequired. Both the first stage and the second stage switch at a fixed frequency for predictable EMI performance. Rectification of the transformer'soutputisaccomplishedwithsynchronousrectifiers. These devices, which are MOSFETs with a very low on-state resistance,dissipatefarlessenergythanSchottkydiodes.Thisis the primary reason that the converter has such high efficiency, evenatverylowoutputvoltagesandveryhighoutputcurrents. Theseconvertersareofferedtotallyencasedtowithstandharsh environmentsandthermallydemandingapplications.Dissipation throughout the converter is so low that it does not require a heatsink for operation in many applications; however, adding aheatsinkprovidesimprovedthermalderatingperformancein extremesituations. This series of converters uses the industry standard footprint andpin-outconfiguration.

ReMOTe SenSe(+) (Pins 7 and 5): The SENSE(+) inputs correctforvoltagedropsalongtheconductorsthatconnectthe converter'soutputpinstotheload. Pin 7 should be connected to Vout(+) and Pin 5 should be connectedtoVout(-)atthepointontheboardwhereregulation is desired. A remote connection at the load can adjust for a voltage drop only as large as that specified in this datasheet, thatis [Vout(+)-Vout(-)]-[Vsense(+)-Vsense(-)]< SenseRange%xVout Pins 7 and 5 must be connected for proper regulation of the output voltage. If these connections are not made, the converter will deliver an output voltage that is slightly higher thanitsspecifiedvalue. Note: the output over-voltage protection circuit senses the voltage across the output (pins 8 and 4) to determine when it should trigger, not the voltage across the converter's sense leads(pins7and5).Therefore,theresistivedropontheboard should be small enough so that output OVP does not trigger, evenduringloadtransients.
