Q48T20050 and Q48S20050 DC-DC Converter Data Sheet

36-75 VDC Input; 5.0 VDC @ 20A Output

The

Q48T20050

through-hole and

Q48S20050

surface

mounted DC-DC converters offer unprecedented perform-

ance 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, excel-

lent thermal performance and a very low body profile.

In telecommunications applications the

Family

20 A con-

verters provide thermal performance that exceeds competing

quarter bricks with a higher nominal rating. 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 extremely high qual-

ity and reliability.
