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.
1 The solder exemption is for customers choosing to use the exemptions for lead in solders for servers, storage and storage array systems, and network
infrastructure equipment for switching, signaling, transmission, and network management for telecommunications.
