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.
