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 40 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 40 A half-bricks. This performance is accomplished through the use of
patended/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.
