QL48T30 Family Data Sheet

36-75 VDC Input; 1.2-0.8 VDC @ 30A Output

The QL48T30 family of low output voltage through-hole

DC-DC converters 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.

Designed specifically to power low voltage silicon de-

vices, the QL48T30 converters provide high-efficiency

single stage conversion directly from a 48 V bus to sub

volt levels, eliminating the need for secondary

conversion. 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, result in products with extremely high quality

and reliability.
