PQ60025ETL35Module
ThePQ60025ETL35PowerQorTeraEighth-brickconverter
is a next-generation, board-mountable, isolated, fixed
switchingfrequencydc-dcconverterthatusessynchronous
rectificationtoachieveextremelyhighconversionefficiency.
The power dissipated by the converter is so low that a
heatsinkisnotrequired,whichsavescost,weight,height,
and application effort. All of the power and control
componentsaremountedtothemulti-layerPCBsubstrate
with high-yield surface mount technology. Since the
PowerQorconverterhasnoexplicitthermalinterfaces,itis
extremelyreliable.RoHSCompliant(seepage13).
