Q48T20050 and Q48S20050
36-75 Vdc Input, 20 A, 5.0 Vdc 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.
Data Sheet
&&
In telecommunications applications the
Q
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 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 pack-
aging, results in a product with extremely high quality and
reliability.
