Q24T25033

Data Sheet

18-36 Vdc Input, 25 A, 3.3 Vdc Output

The Q24T25033 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 25 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 di/dt’s advanced electric and thermal

circuitry and packaging, results in a product with extremely

high quality and reliability.
