Q24T15050 DC-DC Converter Data Sheet
18-36 VDC Input; 5 VDC @ 15A Output
The Q24T15050 through-hole mounted 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 theQFamily 15 A con-
verters provide thermal performance comparable with exist-
ing 20 A designs. Low body profile and the preclusion of
heat sinks minimize airflow shadowing, thus enhancing cool-
ing for downstream devices. The use of 100% surface-mount
technologies for assembly, coupled with Power-One’s ad-
vanced electric and thermal circuitry and packaging, results
in a product with extremely high quality and reliability.
