QD48T033050 DC-DC Converter Data Sheet
36-75 VDC Input; 3.3VDC @ 15A and 5.0VDC @ 10A Outputs
The QD48T033050 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 with total power of 100 W. This is
accomplished by the use of patent pending circuit and pack-
aging 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 @ 3.3 V and 10 A @ 5 V simultaneously
– with thermal performance far exceeding existing dual quar-
ter bricks and comparable to dual half-bricks. Low body pro-
file and the preclusion of heatsinks minimize airflow shadow-
ing, thus enhancing cooling for downstream devices. The
use of 100% surface-mount technologies for assembly, cou-
pled with Power-One’s advanced electric and thermal cir-
