Description
The QmaX
TM
Series of high current single output dc-dc converters set new standards for thermal performance and
power density in the quarter-brick package.
The 45 A QM48 converters of the QmaX
TM
Series provide outstanding thermal performance in high temperature
environments that is comparable to or exceeds the industry’s leading 50 A half-bricks. This performance is
accomplished through the use of patented/patent-pending circuit, packaging, and processing techniques to
achieve ultra-high efficiency, excellent thermal management, and a very low-body profile.
The low-body profile and the preclusion of heat sinks minimize impedance to system airflow, thus enhancing
cooling for both upstream and downstream devices. The use of 100% automation for assembly, coupled with
advanced electronic circuits and thermal design, results in a product with extremely high reliability.
Operating from a 36-75 V input, the QmaX
TM
Series converters 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.
