Technical Specification NQ15W50SGA30 6.0-15.0V Input 0.8-5.0V Outputs 30 Amp Current Non Isolated SMT Surface Mount The NiQor(R) SMT DC/DC converter is a non-isolated buck regulator, which employs synchronous rectification to achieve extremely high conversion efficiency. The NiQor family of converters are used predominately in DPA systems using a front end DC/DC high power brick (48Vin to low voltage bus). The non-isolated NiQor converters are then used at the point of load to create the low voltage outputs required by the design. The wide trim module can be programmed to a variety of output voltages through the use of a single external resistor. RoHS compliant see last page.

C 10/03/08 Page 7 Technical Specification BASICOPERATIONANDFEATURES The NiQor series non-isolated converter uses a buck-converter that keeps the output voltage constant over variations in line, load, and temperature. The NiQor modules employ synchronous rectification for very high efficiency. Dissipation throughout the converter is so low that it does not require a heatsink or metal baseplate for operation. The NiQor converter can thus be built more simply and reliably using high yieldsurfacemounttechniquesonasinglePCBsubstrate. The NiQorseriesofSIPsandSMTconvertersusestheestablished industry standard footprint and pin-out configurations. Input: Outputs: Current: Package: 6.0 - 15.0V 0.8 - 5.0V 30A SMT Foradesiredincreaseofthenominaloutputvoltage,thevalueof theresistorshouldbe: Rtrim-up = 1200 VDES-0.8 or 1200 _ 100 (W) VOUT = 0.8+ where Rtrim-up +100 (W) VDES=DesiredOutputVoltage CONTROLFEATURES REMOTE ON/OFF: The ON/OFF input permits the user to control when the converter is on or off. There are currently two options available for the ON/OFF input described in the table below.Othersmaybecomeavailableifdemandexists. To maintain the accuracy of the output voltage over load current, it is vital that any trim-up resistor be terminated directly to the converter's ground foot, not at the connection to the load. A separate Kelvin connection to the PCB pad for the ground foot is optimal. Trim-down resistors should be terminated at the converter'sSense+pin. Wedonot recommend bypassing the trim pin directly to ground with a capacitor. The voltage gain from the trim pin to output isratherlarge,15:1.Groundbouncethroughabypasscapacitor could introduce significant noise to the converter's control circuit. PROTECTIONFEATURES OUTPUT VOLTAGE TRIM:TheTRIMinputpermitstheuserto adjust the output voltage according to the trim range specificationsbyusinganexternalresistor.IftheTRIMfeatureisnotbeing used,leavetheTRIMpindisconnected. TRIM-UP: To increase the output voltage from the nominal setpoint of 0.8V using an external resistor, connect the resistor Rtrim-up between the TRIM and the Ground pin according to the diagram below. Input Under-Voltage Lockout:Theconverterisdesignedto turn off when the input voltage is too low, helping avoid an input system instability problem, described in more detail in the applicationnotetitled"InputSystemInstability".Thelockoutcircuitry is a comparator with DC hysteresis. When the input voltage is rising,itmustexceedthetypicalTurn-OnVoltageThresholdvalue (listed on the specification page) before the converter will turn on.Oncetheconverterison,theinputvoltagemustfallbelow thetypicalTurn-OffVoltageThresholdvaluebeforetheconverter will turn off. Output Current Limiting:Toprovideprotectioninanoutput over load fault condition, the unit is equipped with internal overcurrentprotection.Whentheover-currentprotectionistriggered, the unit enters hiccup mode. The units operate normally once the fault condition is removed. Internal Over-Voltage Protection: To fully protect from excessiveoutputvoltage,thisseriescontainscontainsanOutput Over-Voltage Shutdown circuitry. This OVP is independent of thetrimmedsetpoint.Assuch,theconverter'sloadisprotected from faults in the external trim circuitry (such as a trim pin shorted to ground). Since the setpoint of this OVP does not track trim, itissetat6.0V.FormoredetailedinformationcontactSynQor technical support.

Figure H: Converter with Additional Output Capacitance Active Load Sharing:Foradditionalpowerrequirements,the SGA30seriesofconvertershaveaparallelfeatureavailable.To implement forced load sharing, the following connections should bemade: * The share pins of all units in parallel must be connected together. The path of these connections should be as direct as possible. *AllON/OFFpinsshouldbeconnectedtogether. Figure E: converter with Input Filter In the SGA30 (surface mount) converters Cin = 20F of high quality ceramic capacitors. With Lin of 1H, Cd should be 100-200F and Rd should be 0.1-0.2W, in most applications. Formoreinformationondesigningtheinputfilterandchoosing proper values, contact SynQor technical support. Adding significant external pure ceramic capacitance directly across the converter's input pins is not recommended. Parasitic inductanceassociatedwiththeinputpingeometryandPCBtraces cancreateahigh-QCLCcircuitwithanyexternalcapacitors.Just a few nano-Henries of parasitic inductance can create a resonance (or an overtone) near the converter's switching frequency. To avoid this high-frequency resonance, any external input filter shouldexhibitanetsourceimpedanceofatleast20mW resistive through this frequency range. This requirement is easily met with the damping elements discussed above. Adding a small amount (a fewF)ofhigh-frequencyexternalceramicwillnotviolateit. Ifusingconvertersathigherpowers,considertheripplecurrent rating of Cd. Contact SynQor technical support for details. Output Capacitance:Itisrecommendedtoaddatleast100F ofcapacitance,withanESRinthe0.1W range, to the output of theSGA30seriesofconverters.Inmanyapplications,however, additional external output capacitance is required to reduce the response to load transients to an allowable level. Forminimalovershootuponrecovery,Cdshouldberelatedtothe minimumin-circuitnetESR. For more detailed derivations of these values contact SynQor technical support. The share bus is not designed for redundant operation and the system will be non-functional upon failure of one of the units when multipleunitsareinparallel.Whennotusingtheparallelfeature, leave the share pin open. SURFACEMOUNTINFORMATION PCB Layout Considerations: SynQor recommends that the customer use a non-solder mask defined pad design. The minimum recommended pad size is 0.074" x 0.122" (1.88mm x 3.1mm) and the maximum pad size is 0.095" x 0.140" (2.41mm x 3.56mm), see the mechanical diagram on page 2. Interconnection to internal power planes is typically required. This can be accomplished by placing a number of vias between the SMT pad and the relevant plane. The number and location of the vias should be determined based on electrical resistance, currentandthermalrequirements."Via-in-pad"designshouldbe avoided in the SMT pads. Solder mask should be used to eliminate solder wicking into the vias. Pick and Place: The NiQor surface mount modules are designed for automated assembly using standard SMT pick and place equipment. The modules have a centrally located inductor component with a flat surface area to be used for component pick-up. The units use open frame construction and have a low mass that is within the capability of standard pick and place equipment. Those modules however have a larger mass than most conventional SMT components and so variables such as nozzle size,tipstyle,handlingspeed,andplacementpressureshouldbe optimizedforbestresults.Aconformaltippedplacementnozzle design is recommended. Coplanarity of better than 0.004" (0.1mm)isachievedthroughtheSMTNiQor'sterminaldesign. Product # NQ15W50SGA30 Phone 1-888-567-9596 www.synqor.com Doc.# 005-2NS163E Rev. C 10/03/08 Page 9 Technical Specification Reflow Soldering Guidelines: Figure J shows a typical reflow profile for a eutectic solder process. Due to variations in customer applications, materials and processes, it is not feasible for SynQor to recommend a specific reflow profile. The customer should use this profile as a guideline only. Since the NiQor surface mount modules have a larger thermal mass and lower thermal resistance than standard SMT components, it may be necessary to optimize the solder reflow profile based on limitations of the other components on the customer board. Sufficient reflow time must be allowed to fuse the plating on the connection to ensure a reliable solder joint. The solder reflow profile should be confirmed by accurately measuring the SMT interconnect leads. Maximum case temperature of260C(exposurefor5secondsorless)isnot exceeded for the NiQor units. Moisture Sensitivity: The NiQor surface mountmoduleshaveanMSLrating1perIPC/ JEDECJ-STD-033A. Input: Outputs: Current: Package: Maximum Temperature (+210-260oC) 6.0 - 15.0V 0.8 - 5.0V 30A SMT Eutectic Solder Melting Point (+183oC) (+150-155oC) Pre-heat Soak *0.5-0.6oC/sec Reflow *1.3-1.6oC/sec *30 Cool Down *< 2.5oC/sec *60 to 90 sec., typ., 2 min max to 60 sec., typ., 90 sec max 2 to 4 min. Figure J: Typical Eutectic (96.5Sn/3.0Ag/0.5Cu) Solder Profile Cleaning and Drying: When possible, a no-clean solder paste system should be used to solder the NiQor SMT units to their application board. The modules are suitable for aqueous washing, however, the user must ensure sufficient drying to remove all water from the converter before powering up. Inadequate cleaning and drying can affect the reliability of the converter and the testing of the final assembly. Product # NQ15W50SGA30 Phone 1-888-567-9596 www.synqor.com Doc.# 005-2NS163E Rev.
