QD48T012018 DC-DC Converter Data Sheet
36-75 VDC Input; 1.2 and 1.8 VDC @ 15A Output
The QD48T012018 dual output through-hole mounted
DC-DC converter offers unprecedented performance in a
quarter brick package by providing two independently regu-
lated high current outputs. This is accomplished by the use
of patent pending circuit and packaging techniques to
achieve ultra-high efficiency, excellent thermal performance
and a very low body profile.
In telecommunications applications the QD48 converters
provide up to 15 A per channel simultaneously – 30 A total –
with thermal performance far exceeding existing dual quarter
bricks and comparable to dual half-bricks. Low body profile
and the preclusion of heat sinks minimize airflow shadowing,
thus enhancing cooling for downstream devices. The use of
100% surface-mount technologies for assembly, coupled
with Power-One’s advanced electric and thermal circuitry
and packaging, results in a product with extremely high qual-
ity and reliability.
