QM48 Series - 45A
The
QmaX Series
of high current single output DC/DC
converters from di/dt sets new standards for thermal per-
formance and power density in the quarter brick package.
The
45A QM48
converters of the
QmaX Series
provide
thermal performance in high temperature environments that
is comparable to or exceeds the industry’s leading 50A 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
QM48T45
converters have a power density of up to
145 W/in
3
, more than twice that of competitors’ 50A half
bricks. Over 2 square inches of board space can be saved
for every slot in which a 50A half brick is replaced with a
QM48T45
converter from di/dt.
Low body profile and the preclusion of heatsinks minimize
impedance to system airflow, thus enhancing cooling for
downstream devices. The use of 100% automation for as-
sembly, coupled with di/dt’s advanced electric and thermal
design, results in a product with extremely high reliability.
Operating from a 36-75 V input, the
QmaX 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.
