reasonthatthePowerQorconverterhassuchhighefficiency,even
atverylowoutputvoltagesandveryhighoutputcurrents.
Dissipation throughout the converter is so low that it does not
requireaheatsinkforoperation.Sinceaheatsinkisnotrequired,
thePowerQorconverterdoesnotneedametalbaseplateorpot-
tingmaterialtohelpconductthedissipatedenergytotheheatsink.

In the positive logic version, the ON/OFF input is active high
(meaningthatahighturnstheconverteron).Inthenegativelogic

REMOTE SENSE(+) (Pins 8 and 6): The SENSE(+) inputs
correct for voltage drops along the conductors that connect the
