Q24S25020 DC-DC Converter Data Sheet

18-36 VDC Input; 2.0 VDC @ 25A Output

Description

The

Q24S25020

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

Family

25 A

converters 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 electronic

and thermal circuitry and packaging, results in a product with

extremely high quality and reliability.
