Isolated
The NiQor 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 page 13).

APPLICATIONꢀCONSIDERATIONS
Input and Output Filtering:ꢀSynQorꢀrecommendsꢀanꢀexternalꢀ
inputꢀ capacitorꢀ ofꢀ eitherꢀ aꢀ tantalum,ꢀ polymerꢀ orꢀ aluminumꢀ
electrolyticꢀtypeꢀonꢀtheꢀinputꢀofꢀtheꢀNQ16ꢀseriesꢀnon-isolatedꢀ
converters.ꢀꢀThisꢀcapacitanceꢀandꢀresistanceꢀprimarilyꢀprovidesꢀ
dampingꢀofꢀtheꢀinputꢀfilter,ꢀreducesꢀtheꢀsourceꢀimpedanceꢀandꢀ
guaranteesꢀinputꢀstabilityꢀ(seeꢀSynQorꢀapplicationꢀnoteꢀ“Inputꢀ
SystemꢀInstability”).ꢀTheꢀinputꢀfilterꢀisꢀformedꢀbyꢀanyꢀsourceꢀorꢀ
wiringꢀinductanceꢀandꢀtheꢀconverter’sꢀinputꢀcapacitance.ꢀTheꢀ
externalꢀ capacitanceꢀ alsoꢀ providesꢀ anꢀ additionalꢀ benefitꢀ ofꢀ
rippleꢀvoltageꢀreduction.
Anꢀ inputꢀ inductorꢀ wouldꢀ helpꢀ isolateꢀ theꢀ rippleꢀ currentsꢀ andꢀ
voltagesꢀ fromꢀ theꢀ sourceꢀ orꢀ otherꢀ NiQorꢀ styleꢀ convertersꢀ
onꢀ theꢀ voltageꢀ supplyꢀ rail.ꢀ Ifꢀ anꢀ inputꢀ inductorꢀ isꢀ used,ꢀ theꢀ
recommendedꢀ capacitanceꢀ shouldꢀ guaranteeꢀ stabilityꢀ andꢀ
controlꢀtheꢀrippleꢀcurrentꢀforꢀupꢀtoꢀ1.0µHꢀofꢀinputꢀinductance.
Theꢀ inputꢀ inductorꢀ needꢀ notꢀ haveꢀ veryꢀ highꢀ inductance.ꢀ ꢀ Aꢀ
valueꢀofꢀ250ꢀnanohenriesꢀwouldꢀequateꢀtoꢀalmostꢀ500ꢀmiliohmꢀ
ofꢀ seriesꢀ impedanceꢀ atꢀ theꢀ switchingꢀ frequencyꢀ ofꢀ 300ꢀ kHz.ꢀ
ThisꢀwouldꢀbeꢀworkingꢀagainstꢀanꢀassumedꢀcapacitiveꢀESRꢀofꢀ
30mWꢀonꢀtheꢀsupplyꢀsideꢀofꢀtheꢀinductor,ꢀprovidingꢀsignificantꢀ
isolationꢀandꢀrippleꢀreduction.
Aꢀ modestꢀ sizedꢀ capacitorꢀ wouldꢀ sufficeꢀ inꢀ mostꢀ conditions,ꢀ
suchꢀasꢀaꢀ330µF,ꢀ16Vꢀtantalum,ꢀwithꢀanꢀESRꢀofꢀapproximatelyꢀ
50ꢀmW.ꢀTheꢀNiQorꢀfamilyꢀconvertersꢀhaveꢀanꢀinternalꢀceramicꢀ
inputꢀ capacitorꢀ toꢀ reduceꢀ rippleꢀ currentꢀ stressꢀ onꢀ theꢀ exter-
nalꢀcapacitors.ꢀAnꢀexternalꢀceramicꢀcapacitorꢀofꢀsimilarꢀsizeꢀ
Noꢀexternalꢀcapacitanceꢀisꢀrequiredꢀatꢀtheꢀoutput,ꢀhowever,ꢀ
theꢀ rippleꢀ voltageꢀ canꢀ beꢀ furtherꢀ reducedꢀ ifꢀ ceramicꢀ andꢀ
tantalumꢀ capacitorsꢀ areꢀ addedꢀ atꢀ theꢀ output.ꢀ ꢀ Sinceꢀ theꢀ
(330µF)ꢀwithꢀaꢀseriesꢀresistorꢀofꢀapproximatelyꢀ50ꢀmWꢀwouldꢀ
internalꢀ outputꢀ capacitanceꢀ isꢀ aboutꢀ 50µF,ꢀ approximatelyꢀ
alsoꢀsufficeꢀandꢀwouldꢀprovideꢀtheꢀfilterꢀdamping.
thatꢀ amountꢀ ofꢀ ceramicꢀ capacitanceꢀ wouldꢀ beꢀ neededꢀ
toꢀ produceꢀ aꢀ noticeableꢀ reductionꢀ inꢀ outputꢀ ripple.ꢀ ꢀ Theꢀ
valueꢀ ofꢀ theꢀ tantalumꢀ capacitorsꢀ isꢀ bothꢀ toꢀ provideꢀ aꢀ highꢀ
capacitanceꢀforꢀpulsedꢀloadsꢀandꢀtoꢀprovideꢀdampingꢀofꢀtheꢀ

Input Over-Voltage Prevention:ꢀ Theꢀ powerꢀ systemꢀ designerꢀ
mustꢀtakeꢀprecautionsꢀtoꢀpreventꢀdamagingꢀtheꢀNiQorꢀconvert-

conditionsꢀ ofꢀ turn-on,ꢀ turn-offꢀ andꢀ loadꢀ transientsꢀ andꢀ faultꢀ

thatꢀcapacitorꢀwouldꢀreduceꢀtheꢀrippleꢀcurrentꢀtoꢀaboutꢀ1.5A,ꢀ
o
