QL48T30012 DC-DC Converter Data Sheet
36-75 VDC Input; 1.2 VDC @ 30A Output
The QL48T30012 through-hole mounted low output voltage
DC-DC converter offers unprecedented performance in the
industry-standard quarter brick format. This is accomplished
through 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
Q&
& Family 30 A con-
verters provide thermal performance that far exceeds all
quarter bricks and is comparable even to existing half-bricks.
Low body profile and the preclusion of heatsinks 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 ex-
tremely high quality and reliability.
