QD48S018033 DC-DC Converter Data Sheet
36-75 VDC Input; 1.8 – 3.3 VDC @ 15A Output
The QD48S018033 dual output surface mounted DC-DC
converter offers unprecedented performance in a quarter
brick package by providing two independently regulated 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.
