Q24S15050 DC-DC Converter Data Sheet
18-36 VDC Input; 5 VDC @ 15A Output
The Q24S15050 surface 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 the Q^&& Family 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.
