QM48S DC-DC Converter Series Data Sheet
40A Output
The QmaX
TM Series of high current single output DC-DC
converters from Power-One sets new standards for thermal
performance and power density in the quarter brick package.
The 40A QM48S converters of the QmaX
TM Series provide
thermal performance in high temperature environments that
is comparable to or exceeds the industry’s leading 40A half
bricks. This is accomplished through the use of patent pend-
ing circuit, packaging and processing techniques to achieve
ultra-high efficiency, excellent thermal management and a
very low body profile.
The QM48S40 converters have a power density of up to
130 W/in
3, more than twice that of competitors’ 40A half
bricks. Over 2 square inches of board space can be saved
for every slot in which a 40A half brick is replaced with a
QM48S40 converter from Power-One.
Low body profile and the preclusion of heat sinks minimize
impedance to system airflow, thus enhancing cooling for
downstream devices. The use of 100% automation for as-
sembly, coupled with Power-One’s advanced electric and
thermal design, results in a product with extremely high reli-
ability.
Operating from a 36-75 V input, the QmaX
TM Series con-
verters provide any standard output voltage from 3.3 V down
to 1.0 V. Outputs can be trimmed from –20% to +10% of the
nominal output voltage (±10% for output voltages 1.2 V and
1.0 V), thus providing outstanding design flexibility.
