Q48T30015 DC-DC Converter Data Sheet

36-75 VDC Input; 1.5 VDC @ 30A Output

The Q48T30015 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 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 heat sinks 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.
